Thanks, Fst.. It does look like it's a Seahawk 6000.
The prop is a few years old now and is in excellent condition. Love it! Everyone should have one. I had originally thought it was a Seahawk but, like Windward, thought they only manufactured in stainless. The stuff you learn on Sailnet.
I need to take it off to get at the stern-tube and then put it back on again afterwards. Have downloaded the instructions from the link you posted and it all makes sense, although dislodging the crustaceans after years of residence to get at those tiny hex screws will be interesting...

Right there is a good reason to read the instructions first - because I would have waded in and stuffed the lot!..
Thanks all for your input.
