Default 07 FX HO knocking noise?

I have a pretty loud knocking noise coming from my 07 FX HO, it seems to be towards the back of the ski, not so much around the engine. It really sounds like a rod knocking, but its not really coming from the engine.. I uploaded it to youtube if you have any ideas I would appreciate it! Thanks


I don't know if this helps, but it seems to be worse when I have the hose off running dry, and when I turn it on its hardly noticeable until I give it a little throttle...

Bend blade on prob or dive shaft? Check the clearance on your prob. Could be a bad bearing on drive shaft.

Yep.... Could do alot of hurt if it's a bent prop/prop shaft/failed bearing.
