-
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.

-
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.
