I’m coming into the home stretch of a dual outboard project. Twin Mark 78A’s on a 1958 Glastron Seaflite.
The second faceplate is one of the replacement plates Mercury offered for this series of motors. It says “merc” instead of “Mark” and has a decal that says “78A.” I think the plate is stamped aluminum rather than the cast original.
I hope to find one of these
I’ll put an ad in the classified section but I wanted to start here.
super project & nice work! I still have some Mark 78 parts but no front covers, sorry wish I did. You might try Joe Poole on the web. His Dad had a Mercury dealership from back in the 50’s. Look up Fergosoon Poole on the web, Joe has many parts from the dealership. Good luck & great project! Love it, no shift cables.
