What information can I supply someone that could lead them to pointing me in the right direction for the propeller size of my boat.

I believe what's going on is a cavitation burn in the propeller. I also believe that the wrong propeller may be on the boat. There is a second one that came with the boat that is smaller in blade size and I'm wondering if I can put this one on.

Is this a question I should take to a local marine dealer?

Also I was told that a chip in the hull can cause this, is that a fact in the matter?

The boat is a 1993 - 19.5 ft Thompson Carrara with a 4.3 Mercruiser and Alpha One Generation II drive.

Thanks.
