Another prop question.

[MattMigues]

Ok so I ordered a 10.5 x 13p because I was turning 5250-5300 RPM with 10.5x14p. Well I guess the 14p I had was worn more than I realized and I'm at 5300 with 13p. It holds the water up about 3/4 trim. Dropping it half inch last time cause porpoising and lost 250. RPM. I can return prop for $30 restock and go down to smallest pitch in the line I'm running. Also if that doesn't get the RPM to 5500 I can raise motor 1/4" or so being I'm able to trim it out so far right now. Speed wise I actually gained 1.5 mph with smaller pitch. Guess cause the cup is new and fresh. Just looking for opinions
