SJ24 Bilge Pump

Reference Information for SJ24 boat owners.

Gil Lund is the Skipper on Snappy Tom and has owned it since 6 months new off the factory floor. Gil has graciously shared his well thought out and much copied bilge pump system diagram and parts list.

These water-sensing bilge pumps work on the principle of impeller resistance. The pump turns on every 2-1/2 minutes for about one second to sense for water. If water is present, the pump will sense the resistance of the water against the impeller and continue to run until all the water is removed. After that, it will resume checking for water every 2-1/2 minutes. A separate float switch is not required.

The Rule model 25S pump has been discontinued and replaced by model 25SA.
