I finally got the boat I bought this spring in the water this weekend and it has minimal forward thrust.

At WOT the RPM's won't come up while in the forward gear. There is alot of water movement from the prop but limited movement. Out of the water with ears on the prop spins and wil rev up to red line on WOT.

Is this cavitation or a ventilation problem? and which ever it is how do I correct it. Really just want to get this fixed so I can have some fun on the water.

If you read the stickies at the top of the page and get us as many details as possible.
You shouldn't rev in neutral over 1500-2000 it could lead to a runaway.
What rpm are you getting and what speed.If any?
