Jet Boat Wont Plane Out

jet boat wont plane out

Re: boat won't go faster than 10 mph won't plane off. no i'm saying it doesn't stay in water. i pull it out every night. never has set in water for long periods. no boat slips etc. boat is at mechanic. over my head. thanks for all your help. ill will post what the problem was when i know.. Re: my boat wont plane out and reach rpms the propeller rests on a rubber hub that is designed to take the impact of a hit and destroy the lower unit. take a scribe and mark the prop in relation to the rubber hub inside of the prop if the marks aren't still aligned then you have a spun hub meaning that the hub is turning without the prop.. If you have a situation where you increase the throttle on your outboard and the boat doesn't go much faster, chances are the rubber bushing in the propeller has failed. when an outboard motor has.
