I clicked on thios thread because I noticed something peculiar on my boat. When running, it will maybe show 12 volts, and when I turn the lights on, it drops down to 10 volts. I'm going to take some tools next time I go and check to see if the gauge is accurate.

Your dash instrument wiring isn't the best, but that's how CC built it. You might say it's normal
When you turn the lights on, you'll probably notice your gas gauge change, your oil pressure change and your engine temperature change. They're not really changing, just the indication is changing due to voltage drop to the instruments when a load powered from the dash wiring is started. You'll see the same thing when you turn the blower on. Your gauge may say 12 volts when running, but you should check battery voltage with a multimeter while the boat is running. It should be more like 13 to 14 volts at the battery if your alternator is working right
