Yes my boat is rated for 300hp, and you just have to know my friend, (he still has the first penny he ever found) he wants my motor strictly for the fuel milage, and thinks he can work through the problems.. No my motor has no warrenty left, and its not that my motor is not running, its just haveing alot of problems. it seems like every time I go out something else goes out on it. I have spent almost $2000.00 on it already just this sumer (coils, map sensor, etc.) and now it is in the shop because it sucked up a reed, I have never even heard of a optimax sucking up a reed. :-X :-X :-X
