starter switch for port engine intermittent issues

[whaddad-searay320]

When I depress the port switch to start my engine i get no beep and it does not turn engine. I replaced both neutral switches and no luck. I pulled the switch out and sprayed WD40 on the contacts and it seemed to improve but it is still intermitent with less frequency. I was looking to replace the switch but cant find one. Help!!

WE had a similar issue on our 370. It turned out to be the fuel pump relay. I know, sounds crazy, but that's what it was.

Start with the basics. What's the condition of the battery for that engine - not just the 12 sitting volts, but using a load tester to see if the battery has staying power when called upon?
