Hi Keith, my name is Jason.
I don't quite understand you, what kind of problem are you having?
In a nutshell you have either a poor electrical connection at the battery, at the key switch, or a bad key switch.
Where you would start is by removing both battery cables, sanding down the cable ends until everything is clean and shiney, reattach them, and then see if there is any difference. If not, move on to the key switch. You will have to look and see how your key switch is wired into the boat. Sometimes they are factory plastic connectors, other times they are butt splice or oring crimp type connectors. If it's the plastic connector type simply unplug it, check the plug for corrosion, and reseat it and see if it makes a difference. If you have splice type connectors, you would cut out the old connectors and re-splice it with new connectors. If there is no change after doing the splicing, then you would replace the key switch. Does that all make sense to you?
Well that was a bit of a waste of my time, why didn't you tell me all that ahead of time?
Are you still with me?
Hello, my name is***** will assist you.
Remove and check all of the connections going to the ECU on the engine. Make sure that they are clean and tight. Also remove and check all fuses on the engine. Take apart the connector between the engine harness and the boat harness on the engine. Ensure that it is all clean and tight as well.
