If you're running too many rpms with your current pitch 3 blade, then the same pitch in a 4 blade would be just right.

Good article on the subject:
Which is Better: 4 Blades or 3 Blades?


I've had really good luck with the Solas Amita props that come with a pressed-in hub, a ready to use package for less than $100. I've had various sizes on various boats over the years. Like I said, I'm a big believer that smaller aluminum boats with smaller engines in the 40 to 60 hp range need a 4 blade for great overall performance and fuel economy.

Interesting. I may grab one to see if it will take my cruise RPMs down a little.

I would look at the Merc 4 blade Spitfire. It is a performance aluminum blade. performance compared to a 3 blade and gain hole shot performance with no speed loss. That is what I use on my pondtoon. Money well spent. Talk to the merc prop tech. Besides, crooks dont steal many aluminum props.
