What to Compare Before Buying
- Power: This pump is 12V, so confirm the boat’s electrical setup matches.
- Flow rate: The stated output is 1100 GPH. Compare that figure with the amount of water you want the pump to move.
- Automation: AutoSense uses stated activation and shutoff points. Make sure those levels fit the way you want the bilge managed.
- Discharge connection: The threaded discharge system should match the hose or fitting plan for the installation.
Before You Decide
Confirm the RM1100B model, the 12V power requirement, and the 1100 GPH rating before choosing an offer. The threaded discharge and AutoSense features also matter if you are matching an existing bilge setup.
Water Level Check and Pump Cycling
The AutoSense system is built around specific water levels and a backup cycle if the sensor is blocked. That makes the stated activation points, shutoff point, and cycling interval useful checks before installation.
