Outboard question

If you can find OEM coils that have been replaced (don't know when they were made) they are almost always OK. There has been discussion, but I've never seen a good workable procedure--to recoat the cracked coils with epoxy. In testing, I've found a few cracked open coils that had been in dry storage, and tested really well.

J / & E are both same engines. Gale made engines are "pretty much" the same but there are differences. Many Gale made had fuel pumps before J/E. Research/ guinea pigs maybe? And some of the Buccaneer / Wards engines had integral fuel tanks where J/E never did--12hp EG

You are probably aware that there are ways to convert the old 2-hose pressure tank systems to fuel pumps.
