If anything the transom is 17 years old now - and probably less able to take the excess power of a modern (probably heavier) engine than the 2str it had on it when built.

Are you prepared to underwrite his insurance cover (including 2M third party cover) if his insurer refuses to pay out because it is being used outside the manufacturer's recommended range? [/QUOTEP

Polwart...As said, I have already trod the same path myself..and MADE SURE with my insurance company that it would NOT compromise my cover, and oh yes,including the 2m third party cover! From their perspective it is the speed of the craft which dictated the cover,AND NOT the engine rating. For my length of boat [5.5m] being 50knts.Further more,one of the e-tecs main attraction [being a 2stroke] is their power to weight ratio...AND the weight difference between the 115 and 130 etec is VERY small.Of course one would take for granted the good condition of any transom[and rest of the craft] when offering advice,I was offering personal practical advice from the perspective of someone who has already done it.Surely that is what makes forums like this of some value.
I'm actually with Polwart on this one . I have seen & dealt with cases where insurers 'knew' all about the bigger engine , but due to a boat being swamped & the engine being more KGs than the manufactrers max they refused to pay .......

Personal choice I suppose ?

The Etec 115 HO is the same weight as the 130 (and only 10KG more than the 115) the HO will kick out about 120-125HP. I really would not worry about fitting the 115HO to your 6 meter.

Yamaha V4 2 stroke 170Kgs
Etec 115HO 177Kgs

Its a superb engine and one of the best in the range IMO.

that doesn't make sense to me. Surely then Etec would market it as a 120/125. I thought the HO range still put out the same HP but with more torque, and possible a different gearbox?

You obviously don't understand their marketing strategy then. The HO's reputedly have in the region of 10% more than their stated HP.

You may be right - either that or I understand it completely and this is what they "want you to believe". I can't see any obvious claims of 10% more power on the Etec website. If its true then they'd presumably be making such claims, instead they seem (either by accident or design) to have generated the "reputation" that they are 10% more powerful.

In fact their website doesn't seem to explain the difference between the engines at all other than being "tuned" and having a better gearbox.

So you have something to backup your claim? like an independent test report showing dyno readings? or even an official statement from Evinrude? or do you believe everything you hear?

I do believe what I hear when I hear it from people who know what they are talking about.
