Hello all -
I need to buy a prop nut for my restoration project and in doing research, I see there are three main types of nut setups available - Jam nut (2 nuts of different size) with pin, Castle nut with pin, and a nylon lock-nut with pin. Looks like most modern inboard boats use the nylon lock nuts but in the interest of keeping my boat as original as possible, did Chris Craft use castle nuts or the Jam nut method out of the factory? I cannot seem to find information on which is more original.
Does anyone have an opinion on which, out of the three they would recommend and why? All and any advice would be appreciated!
Thanks!

What kind of Prop Nut??

Nick, my 1949 Special Runabout, 1949 27 foot cruiser and my 1959 Sea Skiff all had/have a castle nut secured with a cotter pin. I feel the castle nut/cotter pin is the best set-up.
What ever you decide make sure the prop is really tight on the shaft. I have seen the prop loosen up after they are used for a short time and the nut ends up being loose, too. At least with the cotter pin it can't unscrew.
