Yep, like I said earlier the Honda is a big lump but I don't know if it would make vast difference.

What prop are you running?

latest honda 75 weight - 163kg

latest Suzi 90 - 150kg

yammi 90 2 stroke - 122kg



Optimal speed doesn't usualy 't come with low power to weight ratios so i think I think thats good speed your getting.

Also doesn't a four stroke bang on every other stroke and a 2 stroke every stroke I have always felt the power was a little more immediate and smellier and noisier and betterer.

Having said all that I really am impressed bu our Yammies f70 power to weight and sdtunning fuel economy and I'm hearing there is a lightweight F90 out soon

Just been looking at the price of some yamaha 90s on ebay priced from about 2000 - 2500. If I keep this boat I may do the engine change not just for speed but stability too, all that extra weight is obviously no good.
And i'll have to see how much i can get for the Honda.

Eat a little humble pie give a big smile and hope for the best, this usually works. Ive been testing my boats down there since the early 90's, if your sensible they don't mind.

Looks pretty balanced given the waves and small testing ground but its doesnt looks exciting and just looks heavy..were you full throttle at all? Flog the Hongdu and Get a yam 90, it will transform it! there would be 57 kgs difference hanging off the back and for a 2-0 mtr beam boat thats all the difference

I may have a look at different props, but the rev counter is not accurate so i'll need a new one before i go messing around.

Do you still have your boat with that set up ?

No thats not full throttle on the vid that was my youngest getting used to it,He was only doing about 20 - 25 mph.
He's still a bit nervious on it too as he was with me when it started chine walking.
