    Fleetwin,

    Thank you.

    So I would need a 1957 or 1958 18 HP Johnson head.

    I also need a crankshaft, pistons, rods, and bearings to go into the 1958 crankcase.  I have a damaged 1961 powerhead.  Maybe the crank and pistons will be useable and will interchange.

    Like working a puzzle.  🙂
