Well, I have my 73 tri-hull that weish 1600lbs dry, probably what like 1900lbs loaded? With a mercruiser 140 and a pre-alpha drive.

My prop is 14" x 17p and I can only get to about 4250 RPM if I mess w/ my trim.. My timing is fine, points, condenser, cap, rotor are good. Fresh gas, and a carb rebuild.

I'm thinking maybe going to a 19p prop. Would changing prop diameter and keeping pitch the same do anything?

Ayuh,....

You're Already borderline Lugging Now.....

Going to a 19" prop is the Wrong way to be going.......

Your motor sounds like it's down on Power,.... Do a Compression Test.....
