Boat will not plane and RPM's shoot up when I hit 2,000 RPM's?

Need Help??? Not sure what is going on but just took out boat for first time this year and it goes forward and reverse just fine, but once I hit the throttle the RPM's shoot up and sounds like the prop is just spinning and we don't get the boat to plane. I also tried to slowly edge up throttle and same thing happens once I hit the magic number of 2,000 RPM's. The boat runs great as long as I don't go above 2,000 RPM's. Last year before I winterized it took it out many times and no problems, any help or suggestions please.......Thanks

welcome what kind of boat and motor do you have.

If your prop has a replaceable hub, replace it.

If it has a pressed in hub, have a prop shop replace it.

It is a 1994 Caravelle with a MerCruiser motor. I believe a 350 is in it. Thanks

If you have a spare prop...throw it on and see if your problem goes away. Probably a spun hub.
