Marine Impellers & Water Pump Service Parts
Marine Impellers, Impeller Kits & Raw-Water Pump Service Parts
Shop boat impellers, impeller kits, run-dry impellers, water pump service kits, gaskets, seals, keys, wear plates, and raw-water pump parts for outboard, inboard, and sterndrive cooling systems.
Match by engine serial number, pump model, existing part number, hub style, shaft fit, diameter, width, vane count, and kit contents before ordering.
Many impellers look similar but fit differently. Confirm the part number or pump application whenever possible, especially before replacing a kit with an impeller-only part.
Top OEM Impeller Searches
Impeller Brand & Manufacturer Grid
Search Impellers by Engine Brand, Pump Manufacturer, or Aftermarket Reference
Use these search tiles when you know the outboard brand, diesel or inboard engine, generator, pump manufacturer, aftermarket brand, or equipment reference. Final fitment should still be confirmed by part number, pump model, engine serial number, measurements, or a parts diagram.

Impeller Product Paths
Fitment
Part Number First, Measurements Second
Impellers can share the same general shape while using different hub types, splines, shaft fits, widths, diameters, vane counts, and kit contents. Use the engine serial number, water pump model, existing part number, or parts diagram whenever possible.
Why It Matters
Impellers Protect the Cooling System
A worn, cracked, stiff, or missing-vane impeller can reduce raw-water flow and lead to overheating. Regular impeller service helps protect engines, exhaust components, pumps, and the rest of the cooling system.
Search by OEM, old part number, pump brand, engine model, shaft fit, kit type, or service task.
Impellers
Replacement rubber impellers for routine raw-water pump service and cooling-system maintenance.
Kits
Impeller kits and water pump service kits can include gaskets, O-rings, keys, seals, plates, cups, or related parts.
Cooling Support
Pair impeller service with hose, belt, thermostat, strainer, and raw-water pump inspections when troubleshooting heat issues.
Popular Brand Searches
Search by Engine or Pump Brand
If you do not have a part number, brand searches can help narrow the field before confirming final fitment.
Impeller Only or Complete Kit?
Match the Repair to the Pump Condition
An impeller-only replacement may be enough when the pump body, cover, cup, and wear surfaces are clean. Choose a kit when gaskets, keys, seals, wear plates, cups, or housing pieces should be replaced at the same time.
Service
Replace Before Cooling Flow Drops
Impellers are routine maintenance parts. Heat, age, dry starts, sand, debris, long storage, and low water flow can all shorten service life. Inspect the old impeller carefully and account for any missing vane pieces.
FAQ
Marine Impeller Questions
How do I find the correct boat impeller?
Start with the existing part number, engine serial number, pump model, or OEM parts diagram. Measurements can help, but they should not replace exact part 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, scored wear surfaces, or small hardware that should be replaced while the pump is open.
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, vane count, or kit components.
