Hello,

I have a 2005 9hp go-devil i bought from someone used. It runs great and is in great condition. My only question and worry about the motor is that when it runs at a 1\4 of the way open while the prop is in the water the motor makes a knocking sound. Then when I take the prop out of the water it stops. Then when I put it back in the water and the motor has to work, it knocks again. Other than that worry the thing runs like a champ! any thoughts. any other honda owners have this issue???

Thanks.

idk, but knocking is always bad
