How's that then? I'd expect them to both produce 90hp?

Torque figures would be interesting. However, I very much doubt it'll have the grunt out of the hole like a 2 stroke and according to the Op, it was labouring a bit when loaded with a Yam 90 2 stroke so the Honda is highly unlikely to suit.

iv had both a yam90, tohatsu90 tldi and BF90D on my boat and the yam and honda are all but the same in terms of performace but the honda used half the fuel.

Just because it says the hp on the back doesnt mean that the case. It just has to be within +-10% of that figure for under 100kw and +-5% over.

Have you dyno'd them to compare hp?


Oh and what about the Twatsoo? how did that compare to the Yam & Honda?

I would also like to know that, so far only heard that it has a slightly "rough sound" but no other complaints. Price on the 90 tldi is atractive and its not a very heavy engine either. Wonder how it would suite a searider 5.4.......

I havnt dynoed them but they have in the states if you Google around. The point is that how they feel on the back not the numbers. The Yam was running with boysten reeds and laser2 prop, so a nice setup. The Honda was standard with ally prop and the two were the same, (noise and fuel consumpsion aside, as the yam could drink)
The shitatsu was, in fareness really cheap and great on fuel. But i was about 7-8mph down on top end compared to the yam with the same prop and the Honda. I wouldnt be suprised if it was closer to 80hp. Id say, Tohatsu, great for a fishing boat. Yam good 2nd hand sport boat engine for a holiday without paying fuel all year round. Honda, does everthing brilliantly but at a price.

To go back to the original question, another option. Honda is releasing a new revamped 115 here in the states this summer. Depending on your hurry, that may be worth the wait. It slots in between the 90 and the 150 with all the new technology stuff. Don't know when it makes it's way across the pond, but perhaps worth checking out.
