Good day all. I’m considering a prop change. We are planning the great loop that would entail more motoring than normal. I’ve always had an issue with not attaining the RPMs Yanmar wants the motor to and thought I would solve that issue as well. Dose anyone have experience or recommendations. Thanks

Simple answer, get a Max Prop. These are not inexpensive and they can be adjusted to match your engine and transmission. What you will find is increased speed while sailing when the prop feathers and improved control while docking or maneuvering in tight quarters due to the prop walk in reverse. It will take a bit to get used to the new performance in reverse, once you learn it you will not want to go back.

There will be a lot of motoring, however, a lot of the Great Loop can be sailed, Chesapeake Bay, Delaware Bay up the Hudson, through the Great Lakes, and once in the Gulf of Mexico back to Southport.

The Tech support from PYI is excellent and they can provide the settings for the prop.

The Max Prop is a good prop. A fixed blade prop is also an option. I'd suggest you also look into the Campbell Sailor.

I'd say it depends upon your budget and what you think you want for a prop.

I run a standard fixed three blade on my boat and like the reliability. If I were to think I needed either a second prop or wanted to upgrade, I'd go to the Campbell Sailor.

+1 for the Max Prop. As Dave said, it is adjustable, so you can fine tune the pitch to match your engine. I have made small pitch adjustments to my 3-blade MaxProp the last 2 off-seasons to get the best RPM/speed from my little Yanmar 2GM20F.

Also, the reverse thrust is really strong.
