the deep v gives them awesome ride but need a lil more horsepower to run them. Guys who have had 90s have been satisfied but the ones with 115 seem to be stoked. Go 115 if the budget allows but also interested in others opinions

i am was thinking of the 90etec  and also looking at fuel economy,resale later in time and the differance in price is about $6500 thats for the 115 2s yammie just need to know the pros and cons $6500 differance is a lot of cash that can buy a few tank gas and a good few services and beers and is the noise on a 115 that much louder and does it use more fuel than the 90etec in other words can i justify the $6500 or   

Yes they will use approximately 60% less fuel compared to the 115 2 stroke, they are easy to service, servicing costs are a little bit more than a 2 stroke. If you want reliability go the Yamaha. Yamahas back up and after sales support, warranty is second to none. If it was me i'd be spending the extra and going with the Yamaha.

With the E-tec you still have to service them every year and the oil and sparkplugs are expensive, so you are not getting much of a saving.

hows the mercs 90 or 115 are the any good 

thanks glad to hear about the merc  so far yammie  and merc looks good with the  etec i got that itchy feeling in side that warning bell in the back of my mind to many bad thing being  said about etecs so yammie 4s or merc opti mmmm whats the service cost of  merc  and yammie  at pressent i got a 15 yammie so i will see a jump in cost

That would be more correct, although given that the 115 will cruise faster, it is still a bit misleading. My experience so far is that 'apples for apples' a typical 4 stroke is approx 25% more efficient than a late model 2 stroke at cruise and a bit better than this at trolling speeds. It would be nice to think that the latest engines are 40%+ more efficient etc, but if they are I haven't seen or heard of it yet.

go 4 stroke dude ,no messing with oil tanks and as said the resale will be better worth paying the extra for my opinion 

 what does sws mean the tank is 100L should be heeps lol the resale is very important I'm looking at keeping the rig for a very long time so its important to get it right and that why I'm asking my fellow boaties to share their wisdom  and are the  merc opti max better than etec since the technology is similar any one got any merc opti max disappointment

When I first got my Opti 115 it ran like a dream and in fact except for a bit more of a "bark" coming from the exhaust one would struggle to tell the difference between it and a 4 stroke it is so even in the beat. However I had it for about 3 months (it was 2 years old when I got it) when it lost a cylinder intermittently. It was still under warrantee so took it to the agent and they fixed it FOC immediately no questions asked. It was an ignition module on No. 3 cylinder and according to the agent is a known fault with all of the Opti's up to 150hp. Etecs aren't exempt from this either as my friend's 115 Etec fried the computor module and he waited 2 months for a new one to come from Aussie. My point here is every make and model will have a glitch somewhere in their existence especially in the first 3-4 years and if you look hard enough on all of them you will find something. Make sure that what ever you get that you have a good agent close
