Attwood Sahara MK2 S800 24V Automatic Bilge Pump

The Attwood Sahara MK2 S800 24V Automatic Bilge Pump is intended for a 24-volt boat electrical system and provides an 800 GPH nominal pump rating. Its integrated automatic control reduces the need for a separately mounted sensing switch in the bilge. This configuration is Attwood part 5509-7, so check the part and voltage before replacing an existing pump.

Attwood's X-Air impeller is designed to help clear trapped air that could otherwise interrupt pumping through the discharge plumbing. External mounting feet and a serviceable cartridge make the MK2 layout practical where access around tanks or batteries is restricted. SteadySwitch technology helps reduce unwanted control cycling during routine automatic operation.

Plan the outlet and hose route around the available space, and install the unit where bilge water naturally collects. The 24V version requires matching power and circuit protection; it should not be substituted into a 12V wiring circuit. Once installed, test the automatic sensing function with water, inspect the discharge, and make sure the motor cartridge can still be reached for service.
