Diagnostics, Repairs, and Maintenance
The Sherwood 09959K impeller is supplied with an O-ring, gaskets and technical guide. It has 12 vanes and a through key keyway. The neoprene impeller fits on a 5/8" pump shaft and is designed to pump water.
Sherwood marine raw water pumps feature a flexible neoprene impeller that attaches to the shaft. The shaft rotation powers the impeller which transfers water by creating a vacuum on the inlet side and then forcing water out on the outlet side. As such an important component, you should ensure that your pump impeller is always in top condition and that you always use the correct impeller for your application. This will help to ensure the best engine performance and prolong engine life.
Sherwood recommend that all impellers are replaced at least annually (depending on application) to maintain impeller performance, however it is good practice to inspect them often to check for excessive abrasions or damage. It is also recommended that during long periods of being unused, impellers should be removed from the pump to prevent UV deterioration, vanes setting into position and copper bonding of the impeller to the housing. Any impeller issues can lead to engine overheating, the main reason for premature engine wear.
