2012 Glastron 225 GT prop

Hi

Just bought a mercruiser 5.0L Glastron 225GT 2012...

Prop is aluminium 14.25 x 21 pitch but it is not top notch... Problem is I hit the rev limiter when I trim the engine at wot...

Is going with a stainless steel 14.5 x 21 pitch will solve the problem???
Is 14 x 23 pitch is better?

Thanx

What 5.0 ? Mpi ? What rpm is shown when you hit the limiter ? I’m presuming you have a quite low ratio on the drive ? Perhaps a 1.6 ? If you are hitting the limiter. What’s she like at acceleration?
