Hey Kevin,

My name is Tim and I have a 1977 Caprice boat with a 175 Evinrude on the back.

I can’t shut the boat off.

I changed the key switch and it made no difference. My gauges aren’t working properly either, any ideas?

I would check the ground (black) wire for your gauges. This is probably the same ground that connects to the ignition switch. When the ignition switch is turned off, this ground is connected to the Magneto ground (black/yellow wire).

If this ground is not connected, the engine will definitely not shut down and the gauges will not work properly.

Hope this helps,

Kevin
