Stus-List MAX Prop pitch discussion

Chuck, I have used MAX Props since the mid 80’s including multiple Hawaii crossings. (Full disclosure, I have known Frederic Laffitte one of PYI’s owners since before PYI was a company and have sailed over 20K offshore miles with him.) I echo the comments regarding PYI’s recommendations,

Stus-List MAX prop

Here is an update on my MAX prop. I took it to PYI, the estimate came back needing the following parts, blades, hub, and all gears. Basically I will keep my original housing and get a "new" prop out of the deal for 2/3 the cost of a new prop. I should have it back by the middle of next week. --

Re: Stus-List Max prop

PYI has a spec for blade tightness. When it needs manufactured PYI has a program for that which will cost you roughly 1/3 the cost of an new max-prop. Josh Muckley S/V Sea Hawk 1989 C 37+ Solomons, MD On Thu, Sep 26, 2019, 11:26 AM Doug Mountjoy via CnC-List < cnc-list@cnc-list.com> wrote: >

Stus-List Max prop

When I bought Rebecca Leah 2.5 years ago. The surveyor noticed that the prop blades were loose. I pulled the prop and sent it to a local Prop shop. I was just told that it was not repairable by them. My next step is to take it to PYI in Lynnwood WA for their opinion. I my be in the market for a

Re: Stus-List Max prop

I have a 3 blade Maxprop as well. It has worked well in forward and reverse. Has anyone figured out a way to check its feathering action? I presume it is feathering when sailing, but don’t know how to tell. The only thing I can think of would be to sail to the mooring and then dive.

Stus-List Max prop

We went from 3 blade fixed to 3 blade max prop a couple of years ago. Huge difference sailing as expected and I think it backs and fills better than with the fixed prop. I am considering pitching it slightly heavier on the next haul out this winter based on info on this fantastic forum.

Re: Stus-List Max-Prop service

Hey guys I fixed the subject line I too have a Max-Prop and am fond of it though I have little experience with alternatives. I service mine every year by replacing the zinc and greasing it per the manufacturer's instructions. Josh Muckley S/V Sea Hawk 1989 C 37+ Solomons, MD On Mon, Jan 15,

Re: Stus-List Max Prop 3 blade consternation/confusion.

Thank you for the replies. The shaft taper does not seem to be an issue.I placed the spinner housing on the shaft without the key and with the key. The position of the housing doesn't change at all. The shaft key as you can see in the video is captured wholly within the body of the prop "spinner"

Re: Stus-List Max Prop 3 blade consternation/confusion.

When you speek of "play" are you referring to wiggle between the blades, or wiggle on the shaft, or somewhere else? When I grab on blade and hold it still and then attempt to rotate either of the other 2 blades they will rotate +or- ~1/16th of an inch. I've checked this play every time it is

I purchased La Neige last year. She has a 3 blade max prop folding prop. There was alot of slop/play and I removed it and sent it back to the manufacturer. It was refurbished, then returned to me. The local yard, a Max Prop approved installer assisted in the reinstallation. At the time I thought

Re: Stus-List Max prop angle

Double check the size. I think mine is a 16" and I thought it was at 24°. I also suggest getting a laser tach from Amazon. The Yanmar tachs are notorious for being about 200 rpm slow. Mine was. It sounds like you already know that the pitch can only be changed in 2° increments and for every 2°

Give the people at PYI a shout with all the details: engine, reduction gearing, and your boat specs. They will be able to get you far closer on the first try. Jim Watts Paradigm Shift C 35 Mk III Victoria, BC On 23 March 2016 at 19:18, David Knecht via CnC-List wrote: >

I have a 3 blade Max Prop, 17". The surveyor said to adjust propeller pitch to allow the engine to reach top speed in gear. The current settings are for 24 degrees. I think I am supposed to reduce the angle. I do not know how far off the speed is, so I am thinking of starting at 22. Anyone else

Hi All, Here are the results of my Max Prop issues. I have a CC 35 Mk II with a Volvo Penta 2003 28hp with a 2.4:1 reduction MS2B transmission max RPM is 3200. The prop is a left rotation. The Max Prop is 14” and set to 24 deg (X=C, Y=E). This gives 11.6” pitch. The original settings were way

Re: Stus-List Max-Prop settings

Bill, Couple thoughts: If you are getting a max of 3000 rpm you already have too much pitch. I would not go up; I might go down one click. You should cruise at 80% of max rpm or 2500-2600 rpm. I have a 35/3 with a max-prop set to 14 degrees, but my reduction gear is 2.6:1 I get to 3500 rpm

Re: Stus-List Max-Prop settings

Be careful over pitching it cause continuously running the engine below 80% of full load can cause other problems such as coking up the exhaust elbow and glazing the cylinders. Lots of people like the idea of over pitching the prop to run a little faster at a lower rpm. I say, the difference in
