A 20 cubic inch Champion Hot Rod prop will have a prop shaft dia. of 1/2 inch and can have a dia of around 6″ in. If you can get in contact with those who have a need for them, the value varies with the props design, if it is one they don’t have, and could possibly work with their set up.
A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
