P.S. Dropping is not the most common reason for this failure. It is usually caused by cranking the motor with the plug wires disconnected and just dangling. Maximum voltage is generated with nowhere to go. It will eventually find the thinest place in the insolation and burrow through. To keep this from happening ALWAYS ground the plug wires when the spark plugs are removed. The motor should NEVER be cranked with the wires dangling.
ALSO, In order to maintain the magnetism in those antique soft iron magnets, put a piece of iron (old wrench) across the magnetic poles in the flywheel whenever it is removed from the outboard. Need I remind you that this must be removed when the flywheel is installed ? 🙄
