Pontoon outboard cavitates bad

I have a 24 ft pontoon boat with a 50 hp Mercury. With any weight on the front of boat when boat is just over half throttle the prop loses traction in the water or cavitates engine RPM max out and i have to throttle down all the way to regain push from engine. I replaced the trim tab last year the other one fell off somewhere in the lake because it apparently wasnt tight from the factory. Thats the only change i have made to the engine and cant find anywhere if this would cause this problem but i didnt have the problem before.

Any ideas what could cause this or even better a remedy. Thanks in advance for any help,,,,Jim

Does the toon sit level whan not in motion?
Can you lower the motor on the transom?
Is the toon new what brand?
Can you move ant weight back further?

I can't say that I have herd of this before so that's why I need to ask some questions.
