Any suggestions? I'd like a 4 blade Bravo.

24P would be my guess.

Thats what I'm thinking too. 22P will not be enough.

I was out on June 4th. Old Gas 5000 rpm, 52 mph (gps) 55 on the speedo. with a 22p 4 blade bravo 1 (not labbed). I have the black 502 mpi bravo 1 in a 271 sr-1 1993, so I believe it's a 1.65, now that I understand most formulas with the black 502's had 1.65's I've seen recommendations all over the place for 271 props. Wurl seems to have tried them all. makes me wonder if mine would turn a 28.

I have a 242SS 454 330 HP Bravo1 1,50
mirage 21 plus. Seen 50 on the gps (with bottom paint)

Your boat should go closer to -60 mph
