Just for interest, the reason I put the words cotter pin in parenthasis in the post above is because I have a different understanding of th term cotter pin. Here's why:
In the United States, cotter pin (also known as a cotter keyFact|date=August 2007 or a split pin) is a metal
In the UK, the term split pin has traditionally been used to describe the same device. [ [Split Pins Split Pins at Technologystudent.com] ] [ [Split Pins Split Pins at Stig's Stainless Fasteners] ] [ [Split Pin (Cotter Pin) in Stainless Steel Split Pins at Stainless Steel Solutions] ] The term "cotter pin" is reserved for the tapered round
This quote came from here: Cotter pin

It would be unusual for a prop to be installed with a "cotter pin", they are usually set onto the shaft with a keyway with a nut after the prop with a splitpin to secure the nut.
The chances of a keyway stripping to a point where the shaft runs without the prop are pretty remote so I reckon you're going shopping soon.

Thank you. I won't get to it until next Sunday. Bought mask and flippers so I can at least look.
I get it about the zinc. Wish I knew about it last year when boat was hauled and painted.
Wish me luck!

Sacrificial Zincs by Don Casey
In short: When your sacrificial zinc is gone, galvanic corrosion starts eating the metal bits of your boat--things such as your prop, prop shaft... cotter pins... metal thru-hulls...

Thank you Jim and Sailing Dog. The thing is it could well be sitting at the bottom of my dock/slip. The last time I went out it got me home just fine.
So perhaps with the low tides when the boat sank down into the mud it worked it's way off.
Jim asks whether it was an expensive prop. I don't know. Came with the boat last year when I bought it. Guess I'll find out. Regarding zincs. I don't know where to look.
I'll let you know what happens. Guess I am in the market for mask and flippers.

Bad news is: The prop is keyed onto the shaft. So if nothing's happening, sounds like it's Neptune's now. Hope it wasn't an expensive one!

|sailingdog||Are you sure the prop is still attached to the shaft?? If the shaft is spinning, and you're not getting anything, the prop is likely no longer attached to the shaft.|

I should be out on the water now!
I put my Westerly 26 in forward (engine started +running well) and nothing happened. Reverse, nothing happened. Opened up to look at drive train and the shaft was spinning nicely, gears shifted, shaft spun in other direction.
Break it to me gentlly. Am I going swiming?
I din't hit anything the last time I was out. Do these pins in the props just rust out? Anything else it could be?
Thanks for any help. Oh, the engine is Volvo MD 2B diesel.
