Re: Johnson SuperQuiet Elecramatic
Not my favorite engine. Has a belt driven, automotive style distributor, which really isn't bad when working, and there are worse setups. The distributor and rotor are still available new, but the stator does not look like it is available.
Fuel pump is available.
Electric shift is OK when working, bad when not; you must have the correct electric shift control box (throttle) for it.
If you could get spark without spending anything, the compression was good, and the electric shift was complete and worked, then I would give it a "maybe". To make it a good reliable runner would still take some effort from that point, as you would want to redo the wiring since the insulation of that era does not seem to be holding up well, make sure the lower unit was sealed well, and make sure the ignition system was perfect. The carbs and fuel pump should be rebuilt and all fuel lines replaced with alcohol-resistant lines.
