Performance & Design

• Self-Priming Capability: This pump is remarkably efficient at self-priming, capable of drawing water from a dry start up to 10 feet (3 meters) vertical lift.

• Flexible Impeller Technology: The heart of the pump is a flexible Neoprene impeller. This design allows it to handle slightly sandy or silty water without immediate damage, which is common when operating in shallow or murky coastal waters.

• Marine-Grade Materials: To combat the corrosive effects of saltwater, the pump features a bronze body and a 316 stainless steel shaft.

• High-Quality Sealing: It utilizes a mechanical carbon-ceramic face seal to ensure a watertight fit and prevent leaks at the drive shaft.

Technical Specifications

• Flow Rate: Approximately 21.5 GPM (81.5 LPM) at 1500 RPM.

• Port Size: 1" NPT (Internal Thread).

• Mounting: Flange Mount (typically used on various marine engines).

• Drive: Features a spline drive for secure connection to the engine's power takeoff.

• Impeller Part Number: Replacement uses the Jabsco 17937-0001 (Neoprene).

Summary for the User

The 43210-0001 is a reliable "fit-and-forget" component for engine cooling systems. Its bronze construction ensures it won't rust out in a salt-air environment, and the mechanical seal provides a much longer service life than cheaper lip-seal alternatives.

Maintenance Tip: Always keep a spare Jabsco 17937-0001 Impeller and a fresh gasket on board. If your engine's temperature starts to creep up, a worn or "set" impeller is often the first thing to check.
