Why It Matters

Impellers Protect Your Cooling System

A marine impeller is one of the most important service parts in your raw-water cooling system. Worn, cracked, or missing vanes can reduce cooling water flow and lead to overheating.

We carry trusted marine brands including Yamaha, Mercury, Suzuki, Volvo Penta, Sierra, and more for routine service, seasonal maintenance, and cooling-system repairs.

🔎

Search by Part Number

Already have the old impeller, kit box, or parts diagram? Enter the part number in the search bar for the fastest match.

⚙️

Match the Engine or Pump

Similar-looking impellers can use different hub styles, widths, diameters, splines, or kit contents. Confirm fitment before ordering.

⚓

Service Before Failure

Replacing the impeller during regular maintenance is usually cheaper than troubleshooting an overheat after a failure.

Parts Desk Guidance

Impeller Only or Complete Kit?

If your water pump housing and wear surfaces are clean, an impeller-only replacement may be enough. If the service history is unknown, the old impeller is damaged, or the wear plate, cup, seals, or gaskets are worn, an impeller kit or water pump service kit is usually the smarter repair.

Choose an impeller For routine replacement when the pump body is already in good condition.
Choose an impeller kit When gaskets, keys, seals, or related service pieces should be replaced at the same time.
Choose a water pump service kit For a more complete cooling-system service where wear surfaces may also need attention.

Common Questions

Boat Impeller Buying Help

How do I find the correct boat impeller?

Start with your existing part number, engine serial number, pump model, or OEM parts diagram. Measurements can help, but they should not replace exact part-number confirmation.

Should I buy an impeller kit instead of just the impeller?

Choose a kit when the pump has unknown service history, damaged gaskets, worn seals, or scored wear surfaces. A complete kit can save labor compared with opening the pump again later.

When should a boat impeller be replaced?

Inspect it at least once per season and replace it sooner if cooling flow drops, the engine runs warm, the boat was run dry, or the impeller shows cracking, stiffness, or missing vanes.

Can I match an impeller by appearance?

Appearance alone is not reliable. Many impellers look similar but differ in width, diameter, hub design, shaft fit, or kit components.
