Port engine starting problem

[PJM22]

The port side engine in my boat won’t start after the boat sits overnight. It turns over won’t start and it flashes the battery icon with low voltage. All I have to do is pull the 10amp fuel pump fuse and put it back in and the motor starts. After the boat warms up it runs great and will restart. The boat batteries are good. I had a local sea doo machanic look at it and he couldn’t find a problem. Does anyone have any suggestions on how to fix this.

I found corrosion under these connections at the port fuse box. It was causing low voltage and starting problem on the port engine. Disconnect and wire brush was the answer. Start going through all your electrical connections and check for security and corrosion. These connections look perfectly fine to me from the top down and I skipped over them several times. Disconnect your batteries and clean the wires and terminals as well. Could be a few different things buts start with the easy stuff first.

Thanks for your help. I’ll take a good look and make sure everything is corrosion free. I will let you know if I find anything.
