For what its worth… RH 3 blade, 17 dia. max prop, 2.61 reduction
gear 27 hp, I use 18* or 10.4" of pitch and turn within 100 of my
target RPM.

Do you think the Max Prop can be taken off the shaft underwater by a
diver and worked on out of the water and put back on in the water?
It’s either that or get some hang time on a lift to fix the pitch. I
don’t need to haul the boat as I am heading south in a week or so and
had the boat hauled in the spring.

PYI installation instructions advise that the max prop be disassembled
down to the core spinner before removal or installation. There are too
many small critical parts. Hang time in a lift or a short haul is the
prefered method. I’ve removed and repitched mine and it takes some
practice and 3 hands.

That’s what it looked like in the book that came with it. The rpm’s should be 3400 and I’m getting 2800. How much pitch increase would you recommend. Would it be one or two increments?macks011 <macks04@…> wrote:

Check the message thread starting with #4728. Thats a 600 RPM gap
which would require between 4 to 8 inches of pitch decrease. check
the Max prop chart to find the closest correlation between inches
and their degree settings. I would decrease the pitch by 4 degrees
on the first attempt and see how close I came to the target.If I was
more than 200RPM short, I’d decrease pitch by another setting. If
you are underpropped or overpropped by 100 RPM, its close enough.

If your engine is a 3GM30F, It can be equipped with one of three transmission ratios; 2.36, 2.61, or 3.22 : 1. It is probably 2.61 : 1, most are. You can verify that by locating the plaque on either the side of the trans, or the back of the bell housing (that’s where mine is) If that is correct, and you have a three blade 14 in. diameter prop, you should probably set your prop according to line “L” on the chart. That will give you 28 deg blade angle, and 13.9 inches of pitch. If your engine is running “up to snuff”, you should have no problem getting very close to your required(?) 3600rpm. Also, you should really do this by completely dis-assembling the prop so as to start from scratch and be really certain that you have the correct X’s and Y’s.
Good luck…PWMSward <swardfullsail@…> wrote:

Pual,
Wouldn’t that INCREASE the prop from 11.8 to 13.9? How important is this to do now? I’m realizing I’m creating another project when I can least afford it. I’m late leaving Baltimore and need to get to Marathon, if it’s still there in about a month. I think I will have to find crew to help me go offshore to get this accomplished. Any volunteers?
I have had surgery and still can’t leave-at least a 3 week delay as had been expected and still trying to get rid of an iinfection.

Sward,
Yes, a setting of 24 deg. blade angle (11.8 in. pitch) would be a finer (flatter) pitch than 28 deg.blade angle/13.9 in. prop pitch. If in fact your prop is really set @ 24 deg/11.8 pitch and you can’t get any more than 2800 rpm, I suspect you might have other problems. I base this premise on the fact that I presently run a 14" three blade michigan fixed pitch prop with a 14" pitch (it’s stamped right on the prop). If you quantify a standard fixed pitch prop as being 100% eficient, then a MaxProp of the same size/diameter is 97% efficient by PYI’s own admission. This applies to running forward only. A MaxProp is light years more efficient in reverse.
Hope this helps.
By the way, does your engine overheat underway @ 2800rpm?
PWM
PS, Wrong coast to crew for you…P

A three blade is always more efficient, esp in reverse.

Last year I looked at Autoprop and found out that I
did not have enough clearance. this year I called Max
prop and they will sell me a 14" 3 blade for 2240.
They said that the 3gm was probeably not the original
engine. was too much power for a 14 2 blade and the 3
blade would work much better. Does anyone have an
opinion on this.

Bob, If you can send me the reduction ratio stamped on the I.D.plate of your reduction gear I may be able to help. It seems to me that the diameter of your prop is much to small for the engine you have . In broad and general terms, diameter is what gives you push and stopping power. Blade area is capital here. Pitch gives speed. Send also h.p. and max RPM indicated on engine i.d. plate. Weight of vessel and sailing water line length would nail it down.16 in. whether 2 or 3 blade is probably correct. Pitch would also vary vary depending on what you send. Andre.

Bob, Another solution is a longer shaft but to maintain correct distance between strut and prop. you would have to install a longer strut positioned further aft. Difficult in some cases therefore labour expensive. On my one tonner ( a little heavier than your 32 and simillar engine HP and propeller Rpm ) I was able to thin down hull above prop. to an acceptable thicness ( it was 1 1/2 In. thick ) and went to a square three blade prop.with a 60% blade to disc area. 14 " X 14 " . Not the best but it worked for the 6 mo. Bahama trip. Andre.Bob Frew <rfrew@…> wrote: Dear Andre,The ratio is 2.62:1. The problem is the clearancewhich is 1". Thanks, Bob— andre

I have an F-33 and found the Variprop has
a very short hub. They can provide 3 or even 4 bladed and it has a number of
other benefits. They also do custom sizes so the do 15.5” instead of 15
or 16 which are standard sizes (no real cost difference). I played with the
pitch a bit although their calculations were usable. If you mention F-33 to Michael
804-436-0150 www.varipropusa.com fax 804-436-0140 and my name he’ll be
able to look up all the specifications on mine although your 32 would be a bit
different)
I’ve been very happy with it and
have had it for several years.

If you really needed the area and normal
hull clearance to minimize turbulence you could go to a smaller but 4 bladed
prop. I considerd that for my F-33 but decided I could live with a 15.5”.
Not sure which manufacturers offer that I remember Variprop did. If I remember
correctly it was about 25% more in cost for 4 bladed but my memory may be off.

Bob,
Can the hull be ground away and
even reglassed. I
have done this in the past when I changed
from a
folding to a solid prop. for cruising a race
boat.
Do you have a deadwood ( aperture ) clearance
or
hull clearance problem ?Andre.

Dear Andre,The ratio is 2.62:1. The problem is the
clearance
which is 1".Thanks, Bob

If you can send me the
reduction ratio stamped
on
the I.D.plate of your reduction
gear I may be
able
to help. It seems to me that the
diameter of your
prop is much to small for the engine you
have . In
broad and general terms, diameter is
what gives
you
push and stopping power. Blade area is
capital
here.
Pitch gives speed. Send also h.p. and
max RPM
indicated on engine i.d. plate. Weight
of vessel
and
sailing water line length would nail it
down.
16 in. whether 2 or 3 blade is probably
correct.
Pitch would also vary vary depending on
what you
send.Andre.

Last year I looked at
Autoprop and found out
that
I
did not have enough clearance. this year
I called
Max
prop and they will sell me a 14" 3
blade for 2240.
They said that the 3gm was probeably not
the
original
engine. was too much power for a 14 2
blade and
the
3
blade would work much better. Does
anyone have an
opinion on this.thanks, Bob Frew, Freespirit,

Bob, All in all, you could opt for a used 3 blade power boat prop. and save $ 2000.00 It will slow you down 1/2 + knot or so in light to moderate winds over a folder however.
