Folding Prop: How do I remove?

[rbrasi]

I'm trying to remove this prop, but there seem to be no noticeable nuts/bolts/cotters or anything with which to detach it from the shaft. Does anyone recognize this thing? It almost seems like it's one piece, but it can't be.... right?
The picture on the right is the opposite side of the one on the left.

There should be some flats on the sides that you can put a wrench onto. I think these just thread onto where the prop nut normally goes; and are held on with torque the rotation forces keep it tightening when in forward.

You will need something to brace the driveshaft when you are turning the prop with a wrench. You might ask the yard what they normally use; or wait for an answer here. I don't want to give you the wrong advice on this.

IIRC you need to remove the blades to get at the keeper on the shaft, and you'll likely need a puller for the hub even after you undo all that.

See here for an idea:

That's a Martec prop. Here's instructions on how to take it apart.

I had mine refurbished this winter. Worth doing if the blades are "floppy" in the pivot pin.

Excellent stuff. I'll try this. Thanks!

It may be a Martec brand. What it is NOT is a feathering prop. Totally different animal.
Looks like a folding prop.

You're right, of course.... I've fixed the title for the OP.....

Thanks for the semantic correction. Enlighten me please- what's the difference between a 'feathering' and 'folding' prop?

A feathering prop the blades can be aligned so they do not cause drag. aligned with the direction of water flow. folding props the blades fold back in trail to the direction of travel.

Not semantics. Apples and oranges.
