Eliminating Prop Slippage??????
Right now I am getting abot 24.3% prop slippage with a Revolution 4 19P RH 4 blade with a solid black composite hub that measures 14 5/8", going to Steel hub since it keeps getting shredded. Wouldn't I get less slippage by incresing the prop diameter to say like a Bravo 1 which is 15-1/4" in diameter, considering all else being equal, such as pitch. Also does the Bravo 1 have more transom lift than the Rev 4?

What's Up Miguel!
Sounds like you have a major problem in X dimension and prop selection. First off Mercuiser dose not offer the Bravo I 4 blade in a small enough size for you to run. The smallest is 22 pitch. Please email me with some info so we can get your boat dialed in via computer.
