LOL, all good questions! 2004 12' Boss Pilot boat, 25HP Tohatsu. I have a multimeter. I'll pull out the key switch and test for voltage....I've never heard the boat beeping. I did test the kill switch and it stopped the motor. I noticed a few days ago that the harness it's plugged into has wiring going to the ignition switch. My neighbor who had boats for years up on lake Erie thinks it might be designed to alert low oil pressure, or engine overheating. This boat is a very simple design. Several wires broke during a recent storm and I'm still trying to figure out what goes where. There is also a 25amp fuse holder that I'm still trying to place.
thx
