Volvo Penta Crank Mounted Raw Water Pump Rebuild Kit - Impeller and Seal, OE 21214599 / 21214596

Product Overview

This raw water sea pump rebuild kit is designed for Volvo Penta crank-mounted water pumps, as used on GM-based petrol marine engines. A worn impeller or leaking seal reduces cooling water flow and can quickly lead to overheating, so rebuilding the pump at regular intervals is an important part of marine engine maintenance. The kit references Volvo Penta part numbers 21214599 and 21214596.

Installation and Usage

Rebuilding a raw water pump involves removing the pump from the front of the engine, dismantling it, and replacing the impeller and seals before refitting. Lubricate the new impeller as directed and ensure the vanes face the correct direction. If you are not experienced with marine engines, we recommend having the work done by a qualified marine technician. Always check water flow from the exhaust when first starting the engine.
