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.)

We have a Max Prop, 3 blade and a sailboat with a Perkins 4-154 (about
50 hp on a good day) with a lot of hours and Borg Warner transmission
which means we can't stop the prop from rotating by putting the
transmission into reverse or neutral or indeed at all unless we put a
vise grip on the shaft. That's why we got the Max Prop.

CSY44, 13.5 beam, modified full keel. The boat is about 37,000 lbs.
We like the prop.

Why would you want to stop the prop rotating?
