Rule LP900D is a genuine 12V low-profile non-automatic bilge pump rated at 900 GPH / 3407 LPH, designed for tight bilge spaces where a standard pump body is too tall. Rule's current LoPro product information says the LP900D uses a traditional float switch and/or panel switch for operation, stands just 2.4 in. (6 cm) high, and includes multiple discharge-port options for flexible installation.
Key Features
- Genuine Rule LP900D low-profile 12V bilge pump.
- 900 GPH / 3407 LPH open-flow rating.
- Non-automatic design that requires a separate float switch and/or panel switch.
- Low-profile body only 2.4 in. / 6 cm high for tight spaces.
- Includes multiple outlet options: 3/4 in. straight, 3/4 in. 90 degree, 1 in., and 1-1/8 in. fittings.
- 180 degree rotating discharge body and horizontal or vertical mounting flexibility.
- Approximate current draw 4A at 12V with 7.5A fuse recommendation.
Engine Compatibility
This is not an engine-specific part. LP900D is a 12V bilge pump selected by boat bilge layout, voltage, discharge-hose size, and switching setup rather than by engine make or model. Rule's current LoPro materials position it as a compact pump for boats where space is limited and a low-profile pump body is needed.
Serial Number Fitment Notice
Match this pump by bilge space, voltage, hose-routing needs, and switch type rather than by engine serial number. The key checks are whether the boat uses a 12V system, whether a non-automatic pump is the correct choice, and whether the available discharge fittings and low-profile body suit the installation area.
When This Part Needs Replacement
Replace the pump when the motor no longer runs reliably, output drops, the housing is damaged, or the existing bilge pump no longer clears water effectively from the bilge. In practical service terms, pumps like the LP900D are also commonly replaced when upgrading to a lower-profile setup for tighter spaces or when the existing pump no longer works well with the bilge layout. This replacement guidance is a practical inference based on Rule's stated use for tight-space bilge pumping.
Installation Notes
Install LP900D only after confirming the correct 12V wiring, switch arrangement, and discharge-hose routing. Current Rule references state that the pump uses a threaded discharge nozzle, the full discharge body swivels up to 180 degrees, and the aftermarket package includes the available outlet fittings plus a tricuspid check valve to help minimize backflow on the straight fitting.
Alternate/Superseded Part Numbers
Current sources reviewed show LP900D as the active Rule part number for the 900 GPH low-profile non-automatic version. A related model in the same LoPro family is LP900S, the automatic version with sensor-based operation, but it is a different pump configuration rather than a direct interchangeable substitute in every installation.
Parts Desk Insight
With bilge pumps like this, the most important match is usually the shape of the pump and the switching style, not just the GPH rating. LP900D makes the most sense where the bilge is shallow, space is tight, and a separate float or panel switch is already part of the plan.
