I apperently have one of the very few hulls that were sold new from factory as an inboard engine spec. As a runout special to make way for new model these were sold off with a pod/outboard set up and go well. The pod has been shortened a little which improved performance and handling even more. Fitted out with hardtop and a few luxuries , fridge , cooker , toilet ect so possibly heavier than standard. However have been informed the earlier hulls by sea craft (or similar) were even heavier built. Anyways, presently powered with 96 Mercury 150 EFI 2 stroke , fitted with 5blade High Five prop and lento trim tabs . Initially thought this being bottom of ideal power range , surprisingly goes very well. Low hours 450 . Pops up on the plane nicely and makes max revs no problem. The 150hp in the 2.5 block are known to be a strong motor suitable for heavish boats and appears so. Weight 197kg. As plan to get into a bit of gamefishing , more than likely next season , few trips to barrier with overnight stays a later model motor would be preferred. Ideally 4 stroke as any fumes will be more noticeable with hardtop , alot of idling and trolling. As already well documented the compromise being weight . Checking out specs the 175hp suzuki at @220kg , the 200hp not too much heavier.These being new motors and 25k its a hefty capital investment . Checking out second hand options in suzuki , honda and yamaha 175 to 200hp your pushing 260kg. Realise I am sort of answering my own questions so was wondering if any on here with v198 and 4 strokes or big old 2 strokes of these sort of weights might be able to offer there observations. It is going to be a reasonable investment either way so want to get it right first time. Look forward to the boat show so Ican check out all the latest options under one roof, whilst keeping an eye out on the second hand market. Will try and find a photo that shows how she sits now. Thanks.  |

OK What about a 150hp 4stroke , just in case a good 2nd hand one comes along. Anyone been on one or similar size/weight/vee hull with 150hp 4/. thanks

| Without trying to sound like steps, a 150 will be fine if you prop it right.. And don't expect epic performance.. The ideal motor would be the 150hp merc 4 stroke.. |

Just a quick note that the Zuk 150 and 175 are the same block. |

Sound like me? Sry the 1st thing u need to do is establish the loaded weight of the boat.. all up.. including ppl Then with that know what your expectations are for WoT and cruise speed. Do the numbers required to achieve this Then along with the hp/rpm curve match the prop hp requirements to the power curve graph... and add another 15 to 20%. Also take into consideration the extra weight on the stern of a 4s and how that may effect lifting and maintaining the boat over the bow wave...travelling flat or bow in the air....a good indicator of this is when someone moves to the rear of the boat.. how the boat then gets up and how it maintains trim? Without crunching actual numbers.. but comparing to some similar boats of that period another 25 hp could very well make substantial difference in performance and economy.. more so than going from 2s to 4s keep in mind changing models/ brands also changes gear box ratios which also means a change of prop. |

(A few years ago now)
I spent many happy hours fishing out of my Uncles V198. It started with 1986 235hp Evinrude and later
re-powered with a 225hp Yamaha – I saw it on TM last year with a 200Hp Yamaha
on the back now.
My guess is that a 150hp would be the minimum for your V198 with the added weight / windage of the hardtop. But you don't need 225hp - his boat was a rocket ship with the 225hp Yamaha! Also, more importantly I found the V198 did not like weight at the back - we tried a couple of ideas for game fishing, firstly a 15hp 4/stroke Aux to troll with and then replaced it with a Live Bait tank in place of the Aux bracket. The weight down the back drastically changed the handling of the boat. Being a deep Vee the V198 needs a bit of power to get up on the plane, and with the extra weight we added at the back, you really had to lean on the throttle, trolling it was horrible – bow in the air and wallowing around and any extra weight (people) to the back, waves were slopping up the motor and filling the outboard well. Needless to say both ideas were aborted after a couple of weeks. If it was me – I reckon a 175hp Optimax
or maybe a 200hp (2.6) Etec would work well for you. |

Corokid from what Black Max says based on his experience sounds like extra weight at back is going to be an issue - can you shift some other weight forward at same time as repower - shift fuel/battery/storage? Re steps advice - I have been talking to him off here re repowering my boat - I find his ideas valuable - is a bit of a pain calculating weights and numbers but you do it once and get it right and the enjoyment lasts a long time...and my experience is that you should carefully consider all factors including loading of boat, what you want from it before shelling out the cash to avoid disappointment. What is the saying " act in haste repent at leisure" Good luck ------------- Good fishing trip nothing breaks, great trip catch fish. |

   This has been a successful set up for me. Underfloor I have a 300litre fuel tank and carry my oil resevour and twin batteries, in the transom. Usual anchor /chain etc in the forepeak and associated gear in the cabin.Rods,tackle, ice in the cockpit.She handles well at all speads and planes at zero trim. Trims out nicely at high speed too  Backing ups also no major problem however conditions should bear skippers prudent considerations and a good bilge pump/s

Thanks guys Some good solid advise there. Yes already thinking about relocating batteries forward , under the port side king/queen seat console. I am running three batteries , the third dedicated for the 12v fridge only. So definite improvement. Probably run with the existing motor for a while ,while I weigh up my options , although have not had this boat for long I may have to consider doing what a lot of folk do and upgrade the whole rig to suit my requirements.Will be getting bit of a windfall in 18 months so may hold on for a bit. Walu , That bracket looks the business , looks like about 600mm extension?? Probably what mine was originally and has been shortened to 450mm , obviously to bring weight forward , the con being motor can't tilt fully up there fore a custom towing support came with it . Steps , although I am familiar with the theory and calculations involved to obtain power requirements I don't practise it within my field of marine engineering and would have to drag a few old text books out . I will take a stab in the dark and say it would come out very close to 120hp . However as you say add 20% . Thankyou for taking the time to post the info, I have noted you always willing to help out others with similar questions . Have not ruled out a later model 2 stroke in following order yamaha hpdi , Optimax , not sure about etec yet. Looks like you can get a reasonably low hours , under 10 year old for less than half price of new. 90% of use will be fairly local so fuel consumption not a major factor . Thanks again.

PS.... My engine has later cowling and is a carburated OIS engine not the FICH. It's way cheaper on parts than e-tech and gives almost similar fuel consumption as the e-tech. I do my own maintenance and use a local dealer for diagnostics when required.....saves $$$$

Yes already thinking about relocating batteries forward I have asked around about why this is not done as often ..and either get a blank look or some answer that just doesn't add up...no experiance in doing this in boats...automotive, yes. With automotive there are several issues. 1st is voltage drop under loads.. ie the initial milli sec current draw when starter motor engages, and also when starter is engaged....your normal battery leads need to be upgraded significantly and they are not cheap. You will not see any voltage drop under normal loads .. but a V8 starter will pull something like 900 even over 1000 amps in the initial engage then drop back.... Out board starters do not pull these sorts of numbers but its likely to be still significant ....either of these means a significant drop in voltage.. drop in voltage means things like gps/ sounders may close down in the same manner dirty terminals or a battery on the way out does The other issue is insulation / chaffing/ fire And finally when under charge, batteries give off hydrogen gas....so ventilation is a requirement....but unlike gases like Propane/ lpg / fuel, that lay in the bulges, hydrogen is lighter than air.. lot lighter. |

In some ways it makes sense to have batteries forward. The equipment most sensitive to voltage drop is located near the helm - fish finders and other electronics. Voltage drop for these should be kept to less than 3%. Having the batteries close to these reduces cable thickness required to keep voltage drop within acceptable limits. If ventilating a battery compartment it should be vented out near the top of the compartment. |

The rear of the boat is subjected to less impact which can have an adverse effect on battery life, which is generally why batteries are placed in the stern.. Newer battery technology may have superior construction methods to offset/mitigate possible damage from impacts. Also as mentioned above cable lengths can be shorter if battery is located closer to the engine.

Thanks for the input and advice fullas. Have edited post title rather than another thread as both topics at the same end. Thinking of tidying up the transom , the present bracket is galvanised steel as opposed to stainless , solid and well built but not ideal. Something like a portifino set up with step ,bracket and extra flotation incorporated. Maybe even built in tuna tubes and live bait tank. Have the time and engineering related skills , not a fibreglass expert or boatbuilder. So maybe require assistance of a boat builder . Interested to hear any advise , anyone undertaken this or had it done to similar hull? Would existing transom which appears sound have to be removed or could you build the potifino set up then tie it in somehow ? Will incorporate this with new motor with extra flotation compensating for weight of a 200 4 stroke. Yes I am weighing my options up , looking at capital investment depending on motor spend and transom mod wont be cheap. What else can i get for that money . With the existing hardtop and layout she would be a sweet rig , i like the comfort for overnighting . A photo of present set up.  |

| I spent quite a while looking into doing just this on a boat I had a few years ago. I started out thinking of a fibreglass one, like this http://www.trademe.co.nz/motors/boats-marine/parts-accessories/other/auction-878539598.htm" rel="nofollow - http://www.trademe.co.nz/motors/boats-marine/parts-accessories/other/auction-878539598.htm but that is quite an expensive way to go, especially as like you I don't have fibreglass experience. I ended up deciding to fabricate one instead, in fact had I gone ahead I would have copied the one that Walu has on his boat. |

Interesting dilemma Corokid whether to upgrade boat transom/motor or shop for another boat altogether - a couple of questions I asked myself recently were - how long am I intending to keep boat for? What will difference between selling boat and getting replacement be compared to cost of transom/motor upgrade? Am I basically happy with boat except for work proposed? What condition is rest of boat/canopy/trailer - is whole rig getting tired? I decided in end not to repower my boat for now as difference not enough for cost, present motor still had life in it and not sure if I am keeping boat for more than 3 years now so expenditure hard to Justify for what I would get out of it. Is a good exercise to go through. ------------- Good fishing trip nothing breaks, great trip catch fish. |

Yep hit the nail on the head macskipper. Sort of got this to keep me in a boat for a year or two then upgrade to something like a 6.1 or 6.7 surtees with late model motor , had a 5.5 for 8 years so happy to stick to the same. Walked away from a cheaper boat and stumbled accross this one , the misses loves it for the comfort and ride , every time I use it the whole set up impress me , auto anchoring , shelter when needed and that merc is a very strong motor with plenty life left. Just woul;d like something later model with better economy for what I want to do. Due to a promotion at work I financially will be able to move on sooner than expected so there's my dilemma. If i was to put 60 to 70k into a surtees or similar. By the time i upgrade the haines with a new or near new motor, do the transom its going to be 50ish . Think the first option would have the better resale. Decisions Kevin , when you say you fabricated are you talking alloy? Thinking something like this with built in tuna tubes overflowing into portable bait tank as required. Step for outboard .  |

From what I hear you saying Corokid sounds like you would be best to hold off for now as thinking of replacing rig soon anyway - you can buy a whole lot of fuel for upgrade cost and you wont get it all back when selling either. Anyway just think - boat is going to cost you plenty to run and service anyway without spending additional money on upgrading! ------------- Good fishing trip nothing breaks, great trip catch fish. |

Yeh been thinking that , just purchased a platform mounted aux bracket , have a near new 6hp suzuki 4 stroke gathering dust in the garage , had that on my little boat until i upgraded to the smart wave 3.5 , so will be a good back up auxiliary . As you say might as well get use out the present motor until i decide for sure. Better hold off drilling holes in side of hardtop for game pole mounts too. Hard case , sorry for wasting everyones time. Will post Haines on here first when ready to sell , misses going to pull her hair out

crouch and hold ( directed at myself)Actually running with the 6 hp aux on the back for a while will give me a good feel for how the hull handles the extra weight. Not long ago there was a V198 with an early 90's yamaha 225 4 stroke for sale on trade me , that motor must have been in excess of 260kg , not saying it was a good set up. |

| Totally agree with Ohsoslow, Merc 150 4s are now a 3.0 ltr instead of 2.5 and only weigh 206kg. Very nice motor. Mates got a 198 with an old 120 yami on the back and it still go's well. Very good hull, plenty of lift, planing strakes, trim tabs, all go to add to boat performance. I would have throught a new 150 would be fine. Remember tinnies and I have one are very limited as far as hull shape and design. Surtees are great boats but deep V tinnies are very hp hungry, so you can't compare their needs to a glass boat. |

Hence the reason i asked about the 150 4/ suitability , gives me more options , less money , less weight. So if a reasonable used yammy, honda 150hp (less than 10 years old) becomes available I would seriously consider it. Not ruling out other makes just that seems to be more of these around. The 18 year old 150 merc 2 stroke pops straight on the plane no worries without assisting with tabs) , does have a high five prop, 19". Appreciate the 4/ wont have the same punch but I can live with that , not after more speed , economy , reliability and lack of fumes. Been doing some serious thinking . Last but not least , senior management ( the wife) has no qualms about any spending on this boat , it would be a rerun of SCREAM 2 if I announced swapping boats again , to be fair there's been a few Having the misses onboard not to be underestimated , she even got the vacumn out the other day to suck up a few scales on the interior carpet. Her precious Dyson too , not the hand me down given to me for garage ha ha.She even talked me out of selling my smart wave saying having both boats is what I need , see no reason to do anything to upset that deal  Maybe the transom set up can go on hold for a while. Might build one myself to attach at a later date. So back to plan A to avoid being a time waster. Was thinking about half way up the side of hardtop side for mounting game pole brackets , have 12ft kilwell poles with chatfield bases , will make a decent backing plate for the inside. Thanks again for the advise , got to make my own mind up I know , but good to bounce ideas around.

Gotta bounce ideas around to see which bounce and which fall flat.  I also thought that every year that goes by more better cheaper used motors available as early 4S get up graded? One option is to save searches for used motors on trade me and see what comes up over time.

I am never sure exactly what a portofino is - just a platform and outboard bracket, or also an extension of the hull? But anyway, if you want extra bouyancy in the bum while planing you need to extend the hull plates as well. |

Finally got this site half working on computer.. Dave, if it was me with your boat, I would look at getting the Merc 150 4 stroke, more than enough torque to achieve similar performance to what you've got now, I would expect 35kn+ top end, economical cruise around 25kn, and trolling and low rpm work would be awesome compared with current motor. No noticable increase in weight either. (Potentially if you decide to upgrade boat later, could take motor with you, as would be well suited for a 6meter tinny) What I would look into, is either massive trim tabs either side of motor, or look at making a couple of bouyancy boxes either side of motor, increasing hull length a bit, (which should help with trolling) and help keep bum out of the water when stopped. BUT, I'd only do those if they were a cheap easy option, otherwise wouldn't bother. A simple test might be to get a couple of 20 litre drums, and stick them under each side of duckboard at rest, see if bum lifts up at all. |

Macskipper , already got trim tabs , lenco electric with gauges , well guages in the dash which don't work as think there must be something missing in the installation , feedback transducers of some sort? Will look into that . The tabs work really well with a minor adjustment required now a then. First boat I have owned with tabs , completey transform the ride especially with hardtop and crosswind , would be a pig of a thing without them. Ohsoslow , cheers for the lures by the way . Have been looking into the merc option and have to admit it's growing on me.LIght weight , not bad pricing , should be able to go with existing gauges in the dash. The 3.0 ltr block , and two dealers within an hour of home. One that already knows the boat and existing motor as it was on there yard for a while (sell on behalf) , they did previous service on motor too. I have been looking at fabricating flotation boxes under the existing swim steps . Would not extend to lower hull profile so would not affect performance , however as you state , extra buoyancy when stopped or slow running.Would try and avoid fugly boxes , slight angle to follow hull profile/vee , glass over ply with fibreglass forming nice rounded corners. Possibly mount one or two tuna tubesthrough one of these so manual pick up and pump supply underneath. Weighing up incorporating into existing steps or fabricate entire new set ups. Looks like a good winter project , having the other little boat and kayak I wont have to rush , will wait until after bounty hunter comp MikeAqua , the portifino set up shown is sealed so gives extra buoyancy , but as you state won't have any effect whilst underway. Not a problem when underway as I can trim boat with tabs as it is , achieving a plenty of lift without too much trim tab assistance . Mindful of the effect of excessive trimming on tabs is counter productive efficiency due to extra drag , better to set boat weight distribution up and not rely too much on tabs to achieve this I reckon. |

Would replacing the galv steel outboard bracket with an alloy one, perhaps copy the current steel one. Then have a simple duck board setup on each side, solve the Weight problem. I mate of mine did the same a few years back, use thick wall alloy tube, looked real tidy. GRP pods can be quite heavy as well. |

Yeh thought about that , if I was to do that might as well go the next step and go for portifino arrangement similar to previously shown. I got that picture from a boatbuilding company website so have made contact for a quote for similar set up on my boat, see what they come back with. I am fairly realistic on expected cost , will be more than a couple of grand for sure. Looks a lot cleaner than bracket/duckboard in my opinion. Weight not an issue at this stage and with 150hp options not likely to be, ideally want a 4 stroke for intended use and initially thinking I would have to go to 200hp 4/ which on average would be an extra 50kg easy , hence my original concern . Wont have a 10ltr 2 stroke oil tank in the transom locker also , offset slightly by 4/ sump oil , what would that be @4 ltr. I could be overthinking things a little , but do it once , do it right i say.

Just a note. We had an early 150 opti on a 7m Marko and loved the engine. Fuel use was minimal and performance was great. BUT it used to suffer from overheating if we trawled to much. It seemed to us the impeller/pump was to small and as soon as it got any wear at all on the impeller it would overheat at low speeds. Manufacturer said we were dreaming............****as. You mentioned trawling. Also they drop a lung or two at low revs and are a bit rattly and loud at the bottom of the scale. My mates brother still has the boat and it is going great but we all know it's limitations I guess and don't mind living with them. I bet there are tons of guys on here who trawl and don't have this problem with opti's?

Thanks for the heads up Gary , been researching the hell out of direct injected 2 stroked options , mixed reviews with the opti and etec's to be honest. Not going any further on that to avoid upsetting folk , going to be doing a lot of trolling lures and idling whilst softbaiting in close ect , hence the 4/ preference. |

I have a mate who took an inboard out of one of these or similar ( I can ask) and put on a yam 225 4 stroke he got used. would have been an early model as this was at least 6 years ago. Went like a raped ape but was to heavy and he got the motor a bit low as well. Had to watch out for the following wave if you dropped it off the plane to quick! Another mate is currently building a larger boat and fitting an outboard and we are going to make a bracket up for the motor that comes off just above the hull and Has some width to accomodate divers etc and will be enclosed so some of the outboard weight is supported/floated and the shape will help it plane easier as well in terms of the initial stage when the stern tends to bury a bit. At least we hope so................ Perhaps a well made pod can help negate the extra weight for you also?

Thanks Dunwurkn and Kandrew for feedback on your optimax experience. Not saying i have ruled them out , I actually like that sound too. Would my existing merc gauges match a later model opti ( my motor 96) or do you have to go with the smart gauges. Would save a lot of hassle messing around with the dash layout. A lot of the bad press seems to come from the early models , overseas and you cant believe everything you read on forums aye Looking forward to the boatshow to check out new models. The more I think about it I find myself realising forget about the economically viable accounting side of it. Fishing and boats are my passion , its what I do, its who I am. Consider it my mid life crisis . Life is short.

You can believe what you read if I write it. (except the stuff I get wrong) We replaced thermostat etc and when the impeller gets a bit old she will run hot and sound an alarm. If you shut it down and let it reset and restart and take it up to almost planing speed it gets enough flow to cool which is why we think the pump is small and has no extra capacity but maybe it's something with just this motor which seems weird. The impellers are not visibly damaged when removed. It Has not failed to get us home and does not happen often. Still there it is.................just saying. Anyway we gave up trying to fix it and have the impeller replaced at service now regardless, which does cost money.

I have had this exact problem which baffled the local agent.the heat alarm has a 1 degree factory variance. He eventually replaced the water pump housing also and we ascertained that it had warped slightly affecting the impeller performance. Also thier can be a variance in a rubber fuse holder due to age of engine. I am available if you ph me to explain further business hours....cheers ------------- Last week I joined an Anti-Social support group........They won't talk to me! Papamoa fi-Glass Viscount |

Hey Corokid Awesome hulls mate but im a bit biased ;-) My hull originally had an older yamaha 225 v6 the first of the micro computer things.... it lasted around a month... it drank juice faster than we could put it in and it had some rust in the bore we knew it needed a rebuild but loved the hull... and this boat we have watched for over 15 years before we got it but that another story...
Im now running a 150 HPDI on my old girl. I have the full outboard well and last year we put an ali hardtop on the boat, the hard top is a bit ugly but we were trying to get it on the boat for my dad before he died and we had to work with the free front windows i got but quietly stoked with a hardtop! I  now she has the hard top...  I dont have a fridge I am running two batteries and all the electrical wires are on the same side of the bot. I just dropped the drivers king queen and chopped the passengers one up a little as my chilli bin sits underneath.. helps level her out a bit I cant say enough about the hpdi, trolls on 4 cyclinders knocking fuel burn right down, has heaps of grunt to get out of the hole and cruise at about 3800rpm pulling just on 30knots. According to the flow meter that gives me a NM to the litre so shes pretty damn good! I have pulled over 40knots on an absolute mint day back with no canopy up and just two blokes on board so she can get along damn good I just dont know how much she drinks at those revs we didnt have the lowrance that I have now. So many people rate and love these hulls mate build like brick sh*t houses! Been out in some real rough **** around little barrier etc and never been nervous! Enjoy the beast! |

Yellow V198 thanks for sharing the pics and details of your boat with us. You have done your father proud mate. I like the yamaha 150hpdi , some good feedback , does not seem to be many second hand on the market , did you buy new or used. Looks like not available new anymore. Your boat looks mint , the hardtop a little shorter than mine which would be better for fishing . Hull looks very tidy top and bottom , has it been repainted at some stage. Mine could do with underside of hull being painted at some stage. Will probably do myself lying on back under trailer and just move it on rollers to complete. Having a shed to store boat a bonus , might have to put that on my list at some stage. Have just aquired a stainless rocket launcher to fix to hardtop , platform mount auxilary bracket , both from forum members which is fantastic. After a slow start this thread is coming along nicely with lots of valuable information , opinions and more importantly first hand experiences. Much gratitude to you all from me , I am sure it would be of help to many considering the same upgrades on similar boats. Anyone with any relative material please share with us , photos ,etc. Will share one of my favourite photo's of "White Knight"  |

Hey Corokid Never been repainted, I had the white gelcoat repaired under the hull from a wee incident... but only scrapes and Steve at Pennington Boat Builders did an awesome job. I guess I should elaborate on that other story I mentioned, this particular V198 came into our little bach community brand new, it was the boat to have at the time with all the extras you could think of underfloor tank, fuel injection, trim tabs, colour sounder, anchor winch the lot! Anyway this V198 was stored in a shed next to our first little 15ft wooden boat, a good old planning hull running a Ford Anglia inboard, Dad and I would take our boat out whilst this beautiful Haines sat there doing nothing just getting dusty! I said to dad one day we would own a boat like that. We slowly upgraded our boats, got a fleetline sapphire, and then about 3 years after that the V198 got sold to a guy up the valley and left. Around this time dad got sick so we needed a cabin boat so got a Cabin V163 Hainess with a Mariner 90 on it. Great little boat! I got a feeling one night to jump on trade me and bang up popped the boat. I cheekily asked if the guys would part trade a smaller boat as it was too big for him. we went to have a look and since new the boat had only done 283 Hours and she was still pretty good and He was interested in a trade as we took our boat up with us. so he came out with us on the V163 and we went for a run in the big girl and we made some arrangements subject to a motor check! Quietly Dad and I were stoked! Then the motor report came back, even compressions but the base plate gasket had never been replaced and there was rust in the bore but it was rebuildable... so we spoke to the owner did a deal and walked away hoping the motor would turn up trumps. The rebuild was a drama, couldn't get the power head off as it was stuck fast. We even had the boat being picked up by the motor and it still wouldn't come free, right we can cut the adapator plate and go from there, hang on lets price one, none in new Zealand and a new one from the states was over $2k! oh F###!!!! all of as sudden the motor wasn't cost effective to rebuild... we were just in the right place at the right time and the boat shop we were dealing with was repowering the harbour master from the HPDi's to the Suzuki 4 strokes so we managed to swing a deal on one of those motors, I think the boat shop felt pretty stink saying they could rebuild and then it turned into the drama it was. But we brought the motor at 1400 odd hours and were told it has a new power head and gearbox at 1200 hours. Paper work was to follow but it all got too hard... but we had a running boat and touchwood she still kicking along at close to 1900 hours now.. I haven't seen many for sale although my cousin brought a second hand one that was fully rebuild after a bar incident. that was late last year, there is a 300 on trade me at the mo but that looks like an ex race motor with wing steering and a short mid section... $10k aint to bad...hours dependent...

Cool story YellowV198 , bit of a story how I recently come across "White Knight" won't repeat it here , if your interested its in "Show us your rig section" fairly recently so only a few pages back. Being a marine engineer myself, off course I would carry out all the necessary engine checks before purchase. So after getting boat home , thought i better see if engine starts All good Better go for a sea trial , so loaded all my bits onboard . Took oldest boy with me , sea trial lasted two days without a hitch. Caught plenty of fish and pulled into port for a few hours on the second day to take rest of the family out to an island for lunch , then back out again. So passed sea trial no worries. I was so impressed with the hull , hardtop and general layout and extras on the boat , the engine a bonus. Being EFI it starts first time every time , good service history , I should say it had only done 3 hours running since previous service which included compression checks , cooling system overhaul , gaskets and impeller . With a gentelmans agreement with seller I took it without the sea trial etc , so not quite as reckless as it seems. Ah the cockpit shower switch was faulty so all sorted now. |

Yeh don't miss the 2 stroke fumes , more noted with hardtop and tail wind too. New motor a similar weight to the old one , minus the oil tank and auxilary she's effectively less weight at transom. Noise ? Virtually none at idle , a nice throaty growl at cruise speed but not loud , the misses had a louder growl when i had to tell how much a new motor was I decided to go with a local dealer Mark at Mercury Bay Marine(Whitianga) . I was a first time caller to be honest and we managed to put a fair deal together with Mark including the 1000cca battery and prop upgrade , his call as he wants the best performance to keep the customer 100% satisfied. So all good so far. |

Sweet as , good to hear that. Actually thought the old motor went quiet well performance wise , definitely not economy , ouch. Definitely more midrange punch with the new motor and taking it a little easy. Just sorted out battery switches with New switches and VSR , twin battery set up. All ready to put a few more hours in tomorrow
