Is there anyone else out there with an F70 that can share their experience? Maybe I'm wrong but I imagine the F70 is indeed quieter than the equivalent fuel injected 2 stroke. I know 4 stroke Yamahas very well and have been on plenty of boats with fuel injected 2 strokes and don't get me wrong I like them both, I am just not familiar with the F70 on this hull. I was thinking of running with only two 6 gallon tanks. They are more portable and everyone I have spoken with says the engine sips fuel, which is nice.
I have an F70 on my 15, and I get 9 - 10 mpg at cruise of around 4000 RPM. I'd imagine you'd get a bit less, but not much less.
I don't have an eTec, but having heard them on other boats I don't think they're a lot noisier than a 4-stroke, if at all. Don't confuse eTecs with transitional technology FI 2-strokes such as the Optimax or Yamaha HPDI - they're different, and much noisier, beasts. It there was an eTec 70 I probably would have bought it, although I do like my F70.
Most people ask: 2-stroke or 4-stroke?
They should ask: Today's technology, or noisy, smelly yesterday's?
