Jabsco Impeller 6303-0003-P, Nitrile, 6-Blade, 2 Inch Diameter, Single Flat Drive

The Jabsco 6303-0003-P is a nitrile water pump impeller built for reliable, long-lasting operation in marine pump applications. Constructed from durable nitrile rubber, the impeller is engineered to withstand the demands of continuous water displacement while resisting wear from repeated flexing of the blades against the pump housing.

This impeller features a six-blade design for consistent, even water flow, and uses a single flat drive configuration to engage with the pump shaft. It measures 7/8 inch in width with a 5/16 inch shaft diameter and an overall diameter of 2 inches, making it a compact fit for pumps built to this specification. The nitrile compound is molded in black and is sized to seat directly into the pump housing without modification.

Replacing a worn impeller is a straightforward job: remove the end cover screws, then use an impeller removal tool or channel lock pliers to grip the hub and pull the old impeller free. Screwdrivers should be avoided for this step, since they can damage the pump body face and cause leaks. Once removed, the Jabsco 6303-0003-P installs in its place using the same overall dimensions.
