Prop adjustment

[Viperdaddy]

I have a 2000 crownline lpx 7.4l bravo 3. Im running stock 3x3 15x28p and i believe the small prop is a 13x28p. Im running 4800 rpm. Wondering of i go to a 4x3 15 1/2 and 14 1/2 28p xr bravo3 props, will my boat perform any better? Looking to maybe drop rpm a bit and gain a little top end.

What is the WOT (wide open throttle) Merc-specified maximum RPM for that motor? Your first step is see if you're hitting that rpm at top speed with a normal load. If you're close to what Merc recommends, then changing props won't buy you anything.

your at spec RPM now

if you want to gain top end, get more motor
