I have a 1998 Xpress H51 with 90 hp Yamaha motor.
Bought boat used, third owner.
Current prop is Stiletto 31315Y1315 with 9P90 stamped outside.
Can someone tell me what I have, pitch 15 deg?
I can get 40 mph @ 5600rpms before it begins to porpoise, great hole shot, overall runs good, but will slide some on turns.
Prop does need work, clean up on leading edge of blades.
I'm looking to replace with a Turbo 1, 17 deg. based on info I've read here.
Any thoughts or comments welcomed.
Thanks!
