Nice one, Shame about the Yam. Still think I prefer the Yam though, that test would need to be carried out many times for me to think that the ETec was that much better.

Engine trim could make ALL the difference in a test like that. also they said the engines were propped to makers spec - that could mean one was running a 24" versus a 16" on the other - still in spec!!!

That's what I thought, the variables are potentially huge, I don't believe that the difference seen there, would be produced, if two 150's with same final drive, prop, boat weight and trim where hooked together. one would have the edge but I don't think to that extent.....

commercial envolvement me thinks.

total horseshit, no propwash off the Yamaha, it's insulting that they think people are that stupid, but I guess some are. Take a look at your stern wash when you nail it with an outboard, any outboard and then look again at this video..

Two stroke versus Four

I think you'd always get that result from standstill given similar props. Two stoke has more power strokes and that's usually reflected in the acceleration figures. Its not the same at the top end. This doesn't tell me anything new.

E-TEC vs Yamaha 4 strokes around 115 hp

Greetings all outboard enthusiasts.

Well it is time to "refresh" my outboards on my 24' aluminum hulled whale-watching RIB.

Originally I planned to put twin Yamaha 115 4-strokes on it, 3 years ago, but ended up going with the Honda 130s ( a private, "demo" deal ). My Honda dealer is losing Honda line, and is suggesting the Evinrude E-TECs. I could go up to twin 150s ($$) or down to 115s ....... or the Yamaha 115s that I think would do alright too. ...... but how much speed am I going to lose and/or increase gas consumption from my 130s?

The twin 130s (approx 1000 hours) are fully dealer maintained and have alot of life in them, if someone is looking for a great set up (or possibly separately).
