    Capt Ralph, thank you. Yes I talked with them and they are working on a quote to build me a new one. It is the big round one bolted on the outboard side on the block.

    It will hurt ($$), but you will be better off with a new build than finding a used one (somebody else's problems).
    As long as your bent over, inspect well your stb side H/E.
    Also, you have rigid tubes down there. Inspect them well also. I have replaced them with glass tubes before.

    I do luv that engine. ☺☺

    Keep us up on your project.
