i had it installed on a 2000 bayliner capri 1850.
i did havve speed control problems and we ran in rpm mode for the most consistent pull.
The paddle wheel was right in front of the engine... i think if it could have been located further back it would have been better.
the problem was every time i thougt i had the settings perfect a variable like weight in the boat, the person being pulled, goin up river instead of down would change how well it was working.
it was still worth it to use in rpm mode, and i think it would perform better on a larger boat with A larger motor!
