For this application, good performance SS 4 blade props would be the best
choice. They will give you better acceleration, planing speed, and low
speed cruising ability. You will loose a few mph on top end but chances are
your not trying for top end speed anyway. You will definetly like the way
the boat behaves. Prop for right at max rpms on the engines at wide open.

Don't waist your money on aluminum 4 blade or composite 4 blade as you have
too much torque for these props to hold their shape over time.

Hi

I have just purchased a 2950 Proline with twin 225 OceanRunners. I am
trying
to get the best economical cruise speed I can. I was wonderig what would
be
the advantages to a 4 blade prop as apposed to a three blade prop...

Thanks
