I have a 1990 MGI Norman Super Pro 18.5' bass boat. I am looking for a wiring diagram for this boat. Thanks

Did you try the manufacturer? If they don't have one it probably doesn't exist. Boat wiring is very generic. Wiring for the engine harness is usually provided in the "Service" manual for the engine.
