I am experiencing random starting problems with my port 1997 Cat 3116 300hp. The other day I ran it for about 45 minutes, turned it off for about 2 hours, and then it wouldn't turn over. Starboard engine started fine. Emergency start switch did nothing. I could hear the solenoid click for the fuel pump but that was it, no other sound. After about 1/2 hour, it started fine. I took it back to my slip, didn't turn the battery charger on, came back 2 days later and it started no problem. Checked the batteries with a load tester and they are good, and after 2 days off the charger and starting the engine, they read 12.8V. I've replaced the neutral switch. This is the second time this has happened, the last time in Oct 2021 in a lock on the Caloosahatchee. Any ideas would be greatly appreciated.
