Re: yamaha 150 4-stroke prop?
Well Mark you were right. I am now about to try prop number three. The 14x19 was quick at all rpms but at wot with the motor trimmed I only got a hair over 4800 rpms. It was fast though! With the old '86 2-stroke merc I only ever went 34ish (mph). At 4800 with the 14x19 I went 39.5 on the gps, flat calm, no current, 2 people and 1/2 tank of fuel. I just put on a 14 1/2 x 17 to see if I can get over 5000 rpms. I'll post the results.
