If your interested in power over speed, once you figure out the size and pitch of your old prop, get a four blade prop of the same diameter and pitch.
A 4 blade prop will generally drop the rpm by 200. You can gain that back by dropping the pitch size by 1", so if your boat runs well with a 10x13 3 blade, you can get similar performance out of a 10x12 4 blade. A 4 blade will give some stern lift to an aft heavy boat, but it is no excuse for proper loading.
According to the SOLAS website, your boat has a prop diamater of 11.6" and can run anywhere from a 10 to 16 pitch. Unfortunately this is where the black magic comes in. There is no specific formula to determine proper pitch for your boat. It is too variable. What you need is a tach to see what kind of RPM you are turning then you change pitch size from there. I would suggest you start with a 13 pitch 3 blade. I like the SOLAS props, and have a 3 blade and a 4 blade for my boat. I bought them from iboats.com for 60 each. Here are the sizes available for you through them. http://www.solas.com/newweb/propeller/n ... 04&PdKd=AL
