86 4207 Galley Bilge Pump Replacement Help

[Bentone23]

On my ‘96 355 I had a pex hose split and leak a ton of fresh water into the forward bilge. I repaired the line with an inline splice. The lock slid on the splice a year later and we had the same issue again. I noticed my forward pump started popping the breaker on the main panel. I reset it a few times then one time the pump stopped and that breaker was not tripped. I went and bought a new 1500 Rule Matic pump to replace the original Rule flow matic 1200. I installed the new pump. Shoot. No power. I looked up the bilge pump in the wiring schematic and found a second breaker located under the step by the 1/2/all/off switch. It was tripped! Yay! Easy fix. It works now. No more popped breakers.

Those two breakers are separate feeds for the bilge pump. The one by the 1/2/all/off switch is the one that powers the float switch that will activate the bilge pump automatically. The other breaker on your main panel feeds the manual bilge pump switch at the helm. Either one can trip and the other circuit should work normally. But if the one at the 1/2/all/off switch trips the pump will not operate even if the float switch has been triggered by high water.
