Water-pump impeller for inboard/sterndrive pumps replacing Jabsco 18838-0001 / Sherwood 9959 / Volvo 3854286. Sierra designs the replacement around the specified OEM pump geometry and interchange references.

• Application: inboard/sterndrive pumps replacing Jabsco 18838-0001 / Sherwood 9959 / Volvo 3854286
• Function: Circulates raw cooling water through the engine cooling system; a worn, hardened or damaged impeller can reduce water flow and cause overheating.
• Component: Flexible water-pump impeller
• Blade count: 12
• Interchange: Jabsco: 18838-0001; Sherwood: 9959; Volvo Penta: 835512, 3854286; Oberdorfer: 132-0317

Verify the engine model, serial range, pump housing and original impeller number before installation. Inspect the housing, wear plate, key and gaskets at the same time; replace damaged companion parts rather than installing a new impeller into a worn pump.
