i loved my old engine but i had to replace it one day because it through a rod. i did't now that the measured at the engine and not the prop do they still do that or has that changed. so i dont know if that rating is at the engine or prop but i still will never get on plane the top speed i can get is maby 14 knots with me at the wheel and two people in the back. but even if i got the back to back seats do you still think that it would not get on plane with every body sittin up front. o and i stated the dash board i will post pics of the progress later this weekend.
