Kind of a mystery, beeper and trouble light is indicating 3-3 code which indicates a neutral switch fault but the engine mounted neutral switch checks out as OK with the ohm meter. Swapped out the ECU from another boat and still getting the code. Other symptoms, engine will start and idle in any shifter position and the engine will stumble and not go over about 1200 rpm when in gear and underway. The engine control at the helm has no neutral switch so the two brown wires in the Suzuki cable are simply connected to each other and that has been working fine since the repower 6 years ago. Anyone have a clue? I don't think its the neutral switch as I've tried bypassing it with a switched patch cord and all symptoms remain in fault. Simple circuit is driving me a bit crazy
