Rule 3700 GPH Non-Automatic Bilge Pump – 12V – 14A

The Rule 3700 GPH Non-Automatic Bilge Pump (14A) is a powerhouse designed for large vessels and demanding offshore environments where exceptional pumping performance is essential. Delivering an impressive 3700 gallons per hour, this heavy-duty pump is built to handle high water volumes quickly and reliably, making it a top choice for commercial boats, sportfishing vessels, and blue-water cruisers.

The Rule 14A features a rugged, high-efficiency motor engineered for long-lasting performance under constant marine exposure. Its corrosion-resistant housing, stainless steel hardware, and ignition-protected design ensure safe, dependable operation in engine rooms and fuel areas.

A removable strainer base allows fast access for cleaning and maintenance, while vibration-free operation keeps performance smooth and quiet—even under heavy load.
