Best replacement float switch for a 1996. 272 sailfish I want to change all my float switches most of them old and dirty
Good advice. Just monitor/test them reguraly. Install indicator lamps on the panel - it helps detect failures and to know when they are running.If they're working, and the dirt bothers you, just clean them.
How do you test that float switch Doc to make sure it's working??
There is an LED light on it that shows that it is getting juice. Once of twice a year I take it off the radiator hose clamp on which its mounted and turn it upside down. That lets the float ring slide down the center tube and turns on the pump.
You could also flood your bilge, I guess.
