So before I spend the money. There are, I think, four manufacturers of
these props. Autoprop and Max Prop to name two. I'm leaning to the 4 blade
with big Mickey Mouse ear looking shape style. The boat is a Westerly
Berwick. 31' LOD, 25' LWL, 9.5' Beam with twin keels about six tonner.
Engine is a 30HP Volvo Penta with about 120 hours on it. I have room to put
in a reduction gear. I'm leaning this way because of the experience with my
Yamah T9.9 and the wish to put as much of the power curve as possible into
the speed range of my boat.

If you have used any of these and care to comment pro or con let please do!

(The folding blade type and the cockpit control pitch type are out of the
running for acouple of reasons.)

have at it!
