Johnson Pump 09-702B-1 MC97 Impeller Kit, Replaces Sherwood 10615K and Jabsco 18948-0001

The Johnson Pump 09-702B-1 is a complete MC97 impeller kit built as a direct replacement for Sherwood 10615K and Jabsco 18948-0001. Rather than sourcing an impeller and gaskets separately, this kit bundles everything needed to service a compatible raw water pump in one box: the impeller itself, an O-ring, impeller lubricant, and seven gaskets covering 3-hole, 4-hole, 6-hole, and 8-hole patterns.

The impeller is constructed of MC97/EPDM and Neoprene for cooling performance, while Nitrile is used where oil resistance is needed. This material combination is engineered to deliver self-priming capability and to meet engine OEM requirements, so the pump can draw and circulate raw water for engine cooling as designed. The impeller measures 2.57 inches in outer diameter and 1.63 inches in width.

This kit is designed to fit a range of marine engines including Crusader 97179, Chrysler 3675763 and 4142878, Cummins 4B, Onan MDL6, Chris Craft 454, and Pleasure Craft 454. Because the kit includes all the gaskets needed for reassembly along with lubricant, it simplifies a raw water pump service into a single part purchase.
