My boat Penn yan tournament 210 currently has a 15x17 alum 3 blade prop. It runs ok for a mildly heavy boat but I’ve heard others with the same boat claim they see 40mph out of their boat. I’m closer to 35 mph, however at WOT I’m teetering at just above 4100 rpm. I’m being told that I should be looking for closer to 4400 rpm. I’m considering a 15.75”x15” SS 3 blade prop.
recap: (have). 15x17, 4100 rpm, 35 mph
(considering). 15.75x15, rpm???, mph???
can anyone tell me if I’m heading in the right direction for slight increase in rpm and possibly top speed? i know that a change in pitch and a change in diameter have a certain affect but not sure if the change I want to make gets me a little of each benefit
