🔌 Function

The electric submersible pump removes bilge water when energised by a manual switch or compatible automatic level switch.

⚠️ Common Signs of Failure

• Motor not operating
• Reduced flow
• Impeller jammed
• Seal or housing leakage
• Overheated wiring
• Pump cycling excessively

🛠️ Service Notes

• Mount the pump at the lowest point of the bilge where it will actually pick up, sitting level and secured so it cannot topple or shift at sea, and keep it clear of debris that would jam the impeller
• Take the discharge hose up to a loop above the waterline before it turns down to the outlet so the sea cannot siphon back into the boat, and clamp the hose properly at both ends
• Wire the pump on its own protected circuit with cable sized for the length of the run, and make every connection above the level bilge water can reach, using proper waterproof joints rather than tape
• Test the pump and its float or sensing switch by filling the bilge and watching it lift, run and cut out, and repeat the test at the start of each season
• Treat it as a nuisance-water pump rather than damage control — keep the strainer clear and the bilge dry enough that a new leak would be obvious
