The Sierra 8900 is a high-quality replacement impeller designed for marine water pump applications.

Sierra impellers are manufactured from durable neoprene rubber for long service life and resistance to heat and wear.
Best Use — Parts Desk Insight
Ideal for scheduled impeller replacement during seasonal maintenance or after overheating events. Always replace the impeller at the start of each season or every 100–200 hours of operation — whichever comes first. Inspect the pump housing and wear plate for scoring before installation. Do not run dry. Confirm fitment against Sierra's current application guide by engine make, model, and year before ordering.
