3 blade to 4 blade prop change

[Triple777]

I have a 1987 Four Winns Freedom 160. This boat is used mostly for pulling kids on a tube and recreational fun. Prop is currently an aluminum three blade 14.5" x 19" pitch. Thinking about switching to a four blade prop for better acceleration. Boat has a mercruiser alpha one with a 3.0 four cylinder. Any suggestions would be helpful.

Re: 3 blade to 4 blade prop change

If it doesn't have any problems getting up on plane right now with a normal load, a four blade in the same pitch will help with a heavier load and the tuber out back. You will probably lose a couple of mph at wot but the acceleration is worth it.
