1989 175hp mercury black max prop size and pitch advice

[Ladiesluv]

I have a 24ft Harris floteboate. I recently purchased a 1989 175 black max with a 25 pitch ss prop on it. Not looking to pull skiers but do tubing. Boat will usually loaded with 4 to 5 ppl, grill, cooler. I'm looking for best overall performance. Any suggestions would be greatly appreciated.

You would need to know the RPM's at WOT before you can make a change in prop pitch.

the best overall performance for your application would be a 4 blade prop in the correct pitch. What pitch will be determined by your present #'s as asked for above.. Why the 4 blade prop? i your going to pull anyone, you need one
