Description
This automatic bilge pump helps remove water from small boats without relying on constant manual switching. The built in float switch activates when water rises above the base height, then pumps water out through a connected hose.
Choose 750 GPH or 1100 GPH based on your setup. The compact footprint, 12 volt design, and grated base make it useful for small watercraft, bass boats, jon boats, and other boats where bilge space is limited.

Safety first
Confirm the power source is 12-volt DC. Anything higher can harm the pump. Electric wire connections must stay above bilge water level and must not be submerged. Disconnect power before servicing the pump. Do not use the pump for gasoline, fuel oil, kerosene, or any flammable or explosive fluid.
Wiring instructions
Connect the brown-white wire to the positive terminal and the black wire to the negative terminal to use the automatic function. When water rises above the bottom flat surface of the strainer by 40 to 50 mm, the float switch contact connects and the pump starts. When water drops to 20 to 30 mm above the bottom flat surface of the strainer, the float switch disconnects and the pump stops. If the brown wire is connected to positive and the black wire to negative, the pump functions as a regular bilge pump without automatic function.
Fuse and connections
Connect the wires using the provided wire or additional 18-gauge marine wire as needed, following the diagram. Secure wires to prevent accidental pulling. Join the fuse holder to the positive lead between the battery and switch using waterproof butt connectors suitable for 18-gauge wire. Place the fuse holder in an accessible location for fuse replacement. Use the correct fuse amperage shown on the specification chart. Improper fusing or non-waterproof connections can invalidate the product warranty.
Mounting instructions
Check hull thickness before mounting. It should be at least 1/2 inch thick. If not, install a 1/2 inch marine plywood block slightly larger than the pump base in the lowest part of the bilge, glued to the hull with waterproof adhesive. Place the pump on the plywood in the lowest part of the bilge with the outlet nozzle facing the transom and level.
Care and maintenance
Regularly inspect the pump to prevent debris from blocking the impeller or float. Turn the test knob clockwise to check pump performance. To clean the water chamber, detach the pump housing from the base by pressing the sides, then lift the housing off. To clean the impeller, unscrew and remove the impeller guard, clear debris from the pump chamber, impeller, and strainer slots, then reattach the guard, screw, and housing. Periodically inspect electrical connections for water resistance and proper high, dry installation. Avoid household cleaners because they may damage pump materials.
Recommended supplies
A 1/2 inch thick marine plywood block, waterproof adhesive such as marine sealant, epoxy, silicone adhesive, or fiberglass resin, additional 18-gauge wire in brown, brown-white, and black, a thru hull hose set, and a 3 way rocker panel switch.
Internal sensing activates only when water is detected.
