Rule-Mate RM500B 500 GPH 12V Automatic Bilge Pump | Jaycar

You shouldn't have to remember to switch the bilge pump on every time you drop anchor. The Rule-Mate RM500B does it for you — it detects water in the bilge, kicks in, moves 500 US gallons per hour, and stops when the job's done. Same 12V supply as the manual units, but now it runs itself. You set it up once, and it handles the water whether you're at the helm or ashore. One less thing to think about on a long day out

• Automatic operation — no manual switching required
