Which plug did you disconnect?

Customer: replied 7 months ago.
As your looking at the engine from the back of the boat. The plug on the left. Wasnt sure so I plugged it in and tryed the other wouldn't start with either unplugged. But started when cranking after I plugged them both back in.
Expert:  Tan replied 7 months ago.

So is the engine running now or do you still have the same problem.

Customer: replied 7 months ago.
Same problem.
Expert:  Tan replied 7 months ago.

Ok we need to disconnect the 6 pin plug of the engine wiring harness where the boat harness connects to the engine harness. Then you will have to crank the motor at the start solenoid. Jump from the battery cable connection on the solenoid to the yellow/red terminal. Do you have spark and does engine run now?

You will have to disconnect the fuel to shut engine off.
