I am looking to buy/borrow a 23 pitch prop for my Yamaha 90, 15 spline. Aluminum or stainless, doesn’t matter. Just looking to see if it does better than my 21 pitch.
I do have a 19 pitch stainless I will trade/sell if anyone is interested.
What boat is this engine on? I have a Key West 1720 with a 90TLRB and I’d be very interested in what you find out about different props on the Yamaha 90.

It’s on a 1986 16’ Happy Traveler CC. I was turning 6100rpm with a 19p stainless. I swapped to a 21p aluminum I had laying around and picked up 3-4mph and dropped to 5700rpm. This is probably the ideal setup for me but I’d like to try a 23p just so I know. Holeshot actually felt better with the 21p over the 19p.
