Folding prop

[joneaton]

I have a 30'Dufor Arpege sloop and would like to know what are the disadvantages of replacing the 2 bladed prop with a folding prop?

 

[Vic Willman]

I wouldn't think there'd be any disadvantages. You'd get somewhat less drag while under sail, which is an advantage.

Previous folding props had blades that looked a bit like tulips. They weren’t particularly good in forward and were practically useless in reverse because they depended on centrifugal force to keep them open when backing. It was not uncommon for the darn things to not open when you wanted either. They do reduce drag but unless you are racing probably not enough to matter.
Look for newer models that claim to back well. Feathering props are an alternative but expensive and complex but they offer the advantage of three blades for more powerful forward and reverse.

I have a folding prop on my S2 8.5. It's lousy for forward and worse than that for reverse. Backing into a slip is next to impossible with a cross wind or tide. Unless you are wanting to get serious about racing I wouldn't have one.

I had one on the old Ericson and it worked like a champ. The one on my son's Bennetau (same make, but newer) works just fine, also. Wish I could remember the name of the unit. The newer ones can be adjusted without taking the unit apart - can even be adjusted by a diver. The newer ones can also be greased in place. Maybe you will get some 'yea' sayers on here. Luck.

Has anybody ever heard of a folding prop for the Sailboats that have something like a 10Hp Honda outboard hanging down in the water all the time.
This one cant pull the outboard up because the prop wont go through the hole in the Sailboat under the outboard.
It's a 19' or 20' Olympic.

Thud,
Do you mean saildrive?

 

[Thudpucker]

No sir, but thats a very good efficient looking item you posted there.

Nope, this guy's sail boat has a 10Hp Honda, setting in a hole near the stern. He cant pull the Honda up, and it wont tip up, because the hole is too small.
He has to pay a diver to take the prop off the Honda before he can get it up to take it off the boat.

When I saw the Folding prop, I thought maybe there was one made for his Honda.
I better copy this picture and send it to him.
Thanks.

There are a number of older sailboats that had an outboard in a well near the stern. Kind of like a saildrive (an old OMC product), but a regular outboard would be put in the well. Usually you could pull it up for maintainance, but someone perhaps made a permenant modification.

sounds to me like he needs a two-bladed prop for that Honda. Don't know if they still make 'em but I had one on my 7-1/2 Honda years ago.

Yeah Willie, two blades would do it for him.
If you have any hints as far as searching, I'd appreciate them!
