The motor still starts and idles better than any similar motor I know of and runs well thru the rev range. It's possibly heavier than other tinnys as Alicraft were a jet boat manufacturer and from memory were 6mm hull and 5mmm sides and built strong. Top speed has been 29 knots, I think revs around 5500. When I've been out its usually 2-3 pob and used for fishing with no heavy loads on board. There are no visible numbers on the prop without taking it off so it could be under propped, it does perform beautifully in everything except top speed and economy. It is a stainless prop and from a lot of reading on here the engine height looks right. The last couple of years have been rough and two weeks ago I bit the bullet and advertised the boat, then I got a break, a small mortgage that reduces my debt repayments by 80% and allows me to upgrade a few things that need it and I think I'd have a lot more confidence with a later model and more economical outboard. Steps I can now see that more HP is a good way to go thank you. 68 year old pensioner so economy is much better than speed |

Mejiro wrote: Thank you again, 1951 for me Steps but 52 was a good year too The boat and outboard are both 1993. 4 stroke would be ideal but beyond my budget specially allowing for unexpected costs. I know with an Opti I'd need at least a new battery. I have a very good outboard mechanic workshop across the road and a mechanical godson who has impressed me with repowers for family and friends who is very keen to help and will be my main fishing buddy up here so that will help save some expense I have already decided to repower so now it comes down to what I repower with. A 135 Opti sounds good but I had one on a 6.1 Bluefin and to me it was overt powered so from that, a 115 seems like a good option. Depending on what's available when I get the funds a 135/40 conventional 2 stroke may be what I go for. I'll keep an eye on here and let you know and while I'm here, if any of you ever get the urge to come up for a fish, peace and quiet and about 120 minutes to the Taipa boat ramp, there's enough flat ground on my 2 1/2 acres for a couple of tents and parking for cars/boats and once my boat is sorted you're welcome to come out on that also. |

The difference in economy thru to hull performance in chop is very dramatically different..total different seemingly hulls. A 6.1 blue finwould be min powered 175 (maybe a bit higher) well in the 200 hp range a 115 seems like a good option Thats a min for a boat around the 1200kg mark.. like a SN commander 3 guys up 80L tank full Depending on what's available when I get the funds a 135/40 conventional 2 stroke may be what I go for. That well (nicely) powered for the commander and other similar like 5.5 rayglass I picked up my V6 150 93hrs full service history winterized every yr, ex taupo engine for 9K Cost to swap the 115 out new in around $30 to $50.. sealant etc as have my own home workshop engine hoists etc. Sold the 115 for 7K We estimate your boat around the 1700/1800 thats about the weight of a buccaneer 635.. That nicely powers is around 200hp min 175. The difference between a nicely powered and a min.. A 6m or 6.5 hull will be more uncomfortable and slower and use far more gas working the throttle, in a bit of chop and even more so if chops up than a smaller 5.5m well powered Its not about speed, but if you want to get somewhere quick and dont mind the extra fuel, you can do so... at a fast cruise. Havnt been up there for near on 40yrs And yeah I know the fishing is good up that way... |
