Boat sitting 8 years in desert, $40 dollars later, I got it to start. Problem is engine starts right up, but dies as soon as I let go of key. I can put 12v to + side of coil directly from battery and it runs great, But when I turn key off it stays running till I disconnect the the direct 12v from coil.

check wiring for corrosion and rat bites near switch. You need wiring for specific MC and motor.
