from earlier post second question, have "86" 4.3 liter cobra, with 14.5 x 19 3 blade prop. what are the pros and cons of 3 vs. 4 blade??
 
The more blades, the better hole shot to an extent. The 3 blade will outperform the 4 on the top end most of the time. I have a 22' daycruizer with a Mercruiser 260/Alpha ! and I prefer the 4 blade over my back-up 3 blade. These are both SS.
