I just bought a 2005 Catalina and when I pulled the boat out and started cleaning the prop I noticed some cracks. Long story short the prop is a 13" diameter by 11 pitch 3 blade. It also is a 1990 don't ask me cuz I don't know how that could happen. What I would like to do is put on a new 3 blade fixed prop before I put it in the water. On my sea trial it seemed like the boat didn't have problems reaching 3000 RPMs, but I am not sure if that is the proper size for the boat. Any 310 owners out there I sure could use a little love.
