The pump on my c-27 has a separate fuse for the float operation. It's gone bad before (corroded). When this happens, the pump will operate with the control panel switch but will not operate automatically with the float. You might want to trace the wire back to see if there is an inline fuse holder with a bad fuse before you replace the float or switch..

I think the pump stopped working last fall. I did check the fuse in the electrical panel and it is still good. Raising the float does nothing. The float was replaced when I bought the boat in '98; the pump doesn't look much older. How do I determine whether the problem is in the float or the pump? Or do I just replace both with a pump with an integrated float? Bob Mann
