yamaha 90 or 115 on a ribcraft 5.40...

Hello,
i'm planning to buy a new engine (second hand) for my ribcraft 5.40.
right now i've a 2 stroke mariner 75 hp, i'm looking for a 2 stroke (i prefer 2 stroke) 90 or 115 hp.
i would like to know if someone can tell me either consomption with a 90 or 115 yamaha V4 2 stroke on that boat.
115 is heavier than the 90, so i'm not sure it's really valuable,
thank you for your advice,
Eric.

The V4 is quite a thirsty motor over the 3 pot 90. Your trouble will be finding a decent 90 though as they are few and far between.

Could you up the 75 to a 90, is it not just a carb change?

130 Etec, I think 90 would be disappointing performance wise & the 130 weighs the same as the 115 so daft not to go with the extra hp. The DI would be more economical than the carbed 2s.

130 is not the same price, i don't need that much, i guess
