Rule 1100 GPH Bilge Pump 12V — 29-27DA Submersible Marine Bilge Pump
Keep your bilge dry with the Rule 29-27DA — a 1100 GPH submersible bilge pump built for reliable, high-volume water removal on mid-size to larger powerboats and sailboats. Rule is the world’s leading bilge pump brand, and the 29-27DA delivers the flow capacity and durability that boaters have trusted for decades.
At 1100 GPH, this pump moves water quickly enough to handle significant water ingress from rain, spray, or minor leaks, keeping your bilge dry and your vessel protected. The 12V DC motor is compatible with standard marine electrical systems, and the pump can be wired to a float switch for fully automatic operation.

Best Use Case
Best suited for powerboats and sailboats in the 25–40 ft range as a primary bilge pump, or as a secondary high-capacity pump on larger vessels. Mount at the lowest point in the bilge for maximum water removal. Wire to a float switch for automatic operation so the pump activates whenever water reaches a set level — even when the vessel is unattended. Use 1-1/8" discharge hose for optimal flow and route the discharge line to a through-hull fitting above the waterline. Test the pump and float switch regularly to confirm proper operation.
Parts Desk Insights
Bilge pumps are a safety-critical item — customers should never leave the dock without a functioning bilge pump and float switch. When a customer purchases this pump, always ask whether they have a float switch — cross-sell the Rule Rule-A-Matic Float Switch, Rule Rule-A-Matic Plus Float Switch, or the Rule SuperSwitch Float Switch depending on their installation. For the correct discharge fittings, see the Rule 1207R 1-1/8" 90° Barbed Fitting and Rule 1208R 1-1/8" Straight Barbed Fitting. For customers needing higher capacity, step up to the Rule 1500 GPH Bilge Pump 29-02 or the Rule 3700 GPH High Capacity Pump. For a lower-profile option, see the Rule LoPro 900 GPH Low-Profile Pump.
