No further info to add just curious.
You are talking about the props being taken off outboards hanging off the transom of a boat aren't you? Surely not somebody going to the trouble with dive gear to remove the props off the underwater shaft of an inboard? That would seem to me to be an awful lot of trouble to go to.

The props have been removed from the shafts!! Its up to four boats now,

I reckon it would be a lot of trouble for the money.

Selling a 2nd hand prop isn't going to make you rich. Over the past few months I have sold two 2nd hand props, one for $150 and the other for $400 (he over paid!!).

I bought a new Gori two bladed folding for $1400. A few weeks after I bought it a new Gori the same size sold on eBay for $250.

As the thief doesn't know the shaft taper (and often the shaft diameter) until he has it off, stealing one is a gamble that it will be compatible with a specific boat.

Having removed my prop on the hard 3 times over the last few years I respect anybody who can do it under water, especially as the thief doesn't have access inside the boat to hold the shaft. Swinging a hammer under water or getting leverage to loosen the prop would be interesting. A diver I know does do it and he quotes a few hours labour. A thief would need a few tanks of air.

Maybe it is easier on a sail drive, I've never played with one, and the thieves only target them.

Of course, saying your prop has been stolen could be a good way of getting a new one for the price of your insurance excess.

G'day Keith, I thought that might be the case. Getting props off a shaft wouldn't be a profitable exercise.
Aren't sail drive props just on a splined hub?

On a Saildrive with a folding prop,it requires you to back out grub screws,knock out pins to remove the prop blades,which then allows access to the retaining nut.This nut has a locking star washer.
You in effect need allen keys,hammer with drift,screwdriver and socket wrench.
I couldn't imagine anyone going to that trouble underwater to remove a folder and fixed blade props can be bought for peanuts.
Having been on a yacht where the owner proceeded to show me how good it backs up,he slammed it straight into reverse from forward with a resulting 'bang'.
Needless to say the prop was gone and we had to sail a 38 footer from sea onto a tight fore and aft mooring in Wollongong Harbour.(and made it!)
