I happened into a seized 74 6 hp and found another missing the coils, condensors etc so decided to try and swap out the powerheads to get one functioning motor and a heap of spare parts. That went great so far, everything is cleaned up and rebuilt but i can't seem to find a part number for the gasket below the powerhead where it bolts to the exhaust housing. If anyone has a link to a parts catalog or the part number I would appreciate it. This site has been super helpful so far, thanks again.
