Chuck,
Here is the info from the POs documentation that I found on my MaxProp:
16" 2-blade classic 1 1/8" shaft
Universal M35 trans 2:1
Right Rotation 16 degrees
My boat is a centerboard and with the board up and a clean bottom I get
6kts at 2200RPMs.

Hi Chuck,
I had a similar situation with my old cruising cutter with a Gori
folding prop. At expected RPM the cruising speed was ugly and the
engine chugged along like there was no load. Even worse, in a marina I
learn to go full speed in reverse just to get a wee bite.
In my investigation I found the prop's 18 x 12 expected performance
was suitable for a 2:1 transmission. The installed tranny was a 3:1,
which is great for efficiency and performance but only if the prop is
sized right. I think it was mistake when ordered (like 10 years
earlier) but that is a whole 'nother story.
Do you know what degree pitch the current setting is? I have a vague
recollection a Max prop should be around 14 degree for a 2:1 gearbox
and hull speed in the 6.5 - 7 knot range. But don't quote me.. the
last one I set up was maybe 4 years ago.
Cheers, Russ

I have a MaxProp classic, and a Universal 35 on Daydream. The prop
pitch appears very shallow, and when motoring, seems to be slow.
(from memory of last September, 4.5 knots@ 2300rpms)
Any 37+ owners have this combination of prop and engine, and happen
to know the correct pitch for the MaxProp prop?
And cheers from the Michigan Fridge...-12 in the UP this morning!!
