What is your RPM?
If the pitch is too flat (low), it is like being stuck in 2nd gear. You
will accelerate well and have plenty of reserve to punch through chop,
but redline RPM will give you some speed lower than hull speed.
If the pitch is a little too coarse (high), you will hit hullspeed
What's your HP and gear ratio?

Does any 37+ owner with a Universal M35 and maxprop feathering three blade
know their prop pitch? Mine is set at 22 degrees but last year I could not
get beyond 5.5 knots. PYI manual specs that pitch. It looks entirely too
flat to me. Help?!?

Doug,
I found an old survey that indicates that my Martec folding prop is 16x10. Hope
that is what you needed.
Regards,
Dave.

Congratulations on your purchase of a C&C 33 mk1. They are great boats, lovely
lines and a great sail-er. We have owned one for many years, since the 80s and
love her. Perfect size for cruising with a couple and even with a couple of
kids and always performs well on the race course. And we have

I have recently purchased mk1, with missing prop. I have seen several other
models but they have different pitches and sizes. I am looking at Martec
folding props used which I believe were standard.
What is the original spec for this Atomic 4 engine or if you have a newer
better option.

All of the manufacturers of folding props (and their equivalents like the

recommendation for the optimum prop based on factors like boat size, type,

Hi Joanne,
I don't recall anyone offering the simple solution... take the prop
to the local prop shop.
They will have a gauge that can read the pitch of your prop. Bear in
mind that is only a starting point if you are not replacing in kind.
I don't know about the urethane perfect pitch props

Bad shore power wiring and poorly bonded grounds can cause excessive
corrosion. Bad electrical systems on neighboring boats could also
exacerbate your problems. I think most people follow the practice of
unplugging from shore unless absolutely necessary. A top off for the

Joanne — if you’re in fresh water, you shouldn’t need anodes at all. The only
reason I have one on my prop shaft is to keep it from backing out of the hull

Joanne,
Just looked in my C&C manual which has original specs for a whole bunch of
different C&C’s.
My data sheet is dated May 1977:
C&C 30:
Universal engine - 1:1 transmission - 11” x 7” x 7/8” RH (2 blade fixed)
Westerbeke Deisel - 2:1 transmission - 14” x 10” x 1” RH (2 blade fixed)

Here's a quick way to measure the pitch:
