Propellor Help

[Rodney]

I have a 2006 2700 SE with 350 Mag MPI and Bravo 3.3 blade 20 pitch props .Top speed is 35 mph at 5100 rpm.Cruising at 28-29 mph is at 4500 rpm. Can I switch to 4 blade front and 3 blade rear 22 pitch to reduce revs at cruising speed ? Any help would be appreciated....Thanks.

Rodney welcome aboard.

Try using the mercruiser prop calculator on their WEB site to see what it recommends. I have heard of 4 and 3 blade set ups.
