Hey everyone i have a 1971 15 foot trihaul boat with a merc 1150 motor on the back. It currently has a 2 blade 19p prop on it. I ran across a 3 blade 17p prop this weekend for 20 bucks it seemed to be a good deal. Do you think the 3 blade will work better the the 2 let me know it looks like the diameter may be a couple in of inches smaller then the 2 blade let me know what everyone thinks.
