Prop Advice please
Making 45 Knots (2 way average) in the Solent in slight swell and some chop, revs 5150-5350.Using a Laser 21P on Opti 150. We never pull any toys. Any advice on something to add a few Kn to the top end?

Thanks

Bruce

It's essential information! If you look on the little label on the saddle it may say or in the manual for the engine?

My 150 opti says 5250 - 5750 rpm.

So I reckon Bruce you're spot on with that 21"
