I have been looking for the original factory propeller tip clearance. I would appreciate any information on this.
Hunter 356 factory propeller tip clearance
- Thread starter ALNims
- Start date
Problem
I am sure Hunter doesn't ship sailboats with a prop on it and how
I know is it's the dealer who decides what prop goes on the boat.
they sell a boat they ask the buyer what prop they want or when they
get a boat delivered they decide what prop to use.
When my boat was new they talked me out of a folding prop and when ever I would motor is was very hard to get my boat speed and even when the water was like glass top boat speed was still hard to do and if I push max RPM's I would get black smoke and after them telling me the prop was OK I decided
to change to a Flex O fold prop and now 7.5 no problem and sailing has even improved.
I was very happy with my dealer and they did go the extra mile for me in everything except maybe screwed up with the prop.
So what I am saying is know one prop is a standard factory prop,many things on a boat is not always from the factory like batteries don't come with a boat on most sailboats until at the dealer and they decide what to use.
I know this from when I ordered my 2007 H-36 and the dealer would say we can install the gen or other things and they do install most options but wires and some hardware is done at factory.
I check back than what other 356 boats had for a prop and gave that info to
the prop people, and I do have my old prop and if you want info from that I can get it.

We have an Autostream 3 blade feathering prop on our boat that seems to work well. There seems to be 3 or 4 inches of clearance above the prop. The original props were usually 2 blade fixed. I have our old prop mounted on a board as a decoration and it still allows it to be used as a spare.

I have never used the Martec prop. on our boat.
The Autostream prop was on our boat when we bought it.
With the Autostream we generally cruise about 6 kts at 3000 RPMs. The feathering prop makes a big difference sailing and stopping or backing. Autostream told me their props are bit less efficient motoring straight ahead compared to a fixed prop because the blades can not be cupped.

Nick,
Any information would be appreciated I am also looking at a Flexofold prop. Also do you have shaft or sail drive?

Andrew, I found this note on my computer concerning prop size for a 356. I don't know where it came from for sure. I believe it came from the manufacturer of our Autostream prop in Australia.
"The factory specs (via email to me)call for a 15x13 3-blade prop for the 356. Performance should be 6.8 knots at 2600 to 2800 rpm and 7 knots at 3000 rpm (assume flat water and clean bottom). If you have a Campbell Sailor 3-blade prop on a 356 what is the size and performance (speed/rpms).

some 356s came with a 16x12 3 blade - there are 2 different transmission gear ratios that were used. We changed to a 3 blade autoprop but I can't give you the tip clearance - we changed 11 years ago - but I know at the time that plus the 3 props I have in my notes all were good .
Stock Props:
16x13 2 blade
15x13 or 16x12 3 blade
hope this helps

Chuck,
Thank you for the information. What is the size of your your autoprop?

I think my Flex O Fold was 15X13 and think that was what I and flex O Fold
agreed on the 15X13 and the tip measurement is 7 1/2 from the inside
edge of the shaft hole to tip of my old prop,but my old prop pitch was not correct for my H-36 same boat as 356.
But should give some idea what OK.

I've got a 16" H5 series autoprop;the pitch varies automatically and they selected the range based on the std 16" 3 blade data. Great propeller! with a clean bottom we get 7kts at 2400rpm and she accelerates like a banshee in fwd and reverse from stopped, no prop walk, and since the blades swivel freely she seems to shed lobster warps really well.
very easy to maintain
