Location: Mt. Zion, IL | Fix it the right way and upgrade the wiring. These are computers after all and the fluctuating voltage only shortens the life especially when you discharge the battery to the point that they shut off when cranking the outboard. I have wired probably 20 boats for friends and family now. Just for electronics, we use 4 awg to a breaker and then bus bars under the console if there is one. 10 awg for any extensions and solder all connections except the terminals at the bus bar for the finders, live boxes, etc. Tiller boats are a bit different. None have had these issues once adequate wire is installed, but most, even the brand new boats did, especially when it is below 50 degrees out.
