OEM Fitment First

Impellers can look identical but differ by diameter, width, hub, spline, keyway, vane count, compound, and kit contents.

Shop Volvo Penta

Always confirm with engine serial number, pump model, OEM part number, or existing part number before ordering. Cooling parts can vary by model year, drive package, pump supplier, and serial range.

Browse by OEM Clue

Start with the part number, serial number, or pump model.

The safest impeller match usually comes from an OEM number on the old part, box, invoice, pump cover, parts diagram, or engine service manual.

Why OEM Matters

Raw-water cooling parts are serial-number sensitive.

A correct OEM impeller kit helps maintain cooling water flow and reduces the risk of overheating, alarms, broken vanes, and avoidable pump damage.

Many engines use different pump suppliers or kit contents across model years. OEM part-number matching is more reliable than matching by appearance.

PN

Search the OEM Number

Use the exact part number from the old impeller, kit box, invoice, parts diagram, or service manual whenever possible.

SN

Confirm Serial Range

Match the engine brand, model, horsepower, drive type, serial number, and raw-water pump model before ordering.

OEM

Use Parts Desk Help

Send photos, serial numbers, pump markings, and any existing part numbers when fitment is uncertain.

Parts Desk Guidance

Impeller only, OEM impeller kit, or full water pump kit?

The correct choice depends on the pump condition, service history, and what comes apart during the job. If the pump is clean and related parts are known good, an impeller-only replacement may be enough. If gaskets, seals, wear surfaces, or housings are due, an OEM kit is usually the cleaner repair.

Choose an impeller For routine replacement when the pump, gasket surfaces, and related parts are already confirmed good.
Choose an OEM impeller kit When the factory kit includes the impeller plus required gaskets, seals, keys, O-rings, or wear items.
Choose a water pump service kit For more complete cooling-system service involving wear plates, cups, housings, or internal pump parts.
Ask before ordering When you only have photos, partial numbers, a pump casting mark, or an engine serial number.

Common Questions

OEM Impeller Kit Buying Help

How do I find the correct OEM impeller kit?

Start with the OEM part number, engine serial number, pump model, existing impeller number, parts diagram, or service manual reference. Exact part-number confirmation is safer than matching by appearance.

Why not match an impeller by size only?

Many impellers share a similar size but use different hubs, splines, keyways, vane counts, materials, or kit components. The wrong match can reduce cooling performance or damage the pump.

Should I buy the impeller only or the full OEM kit?

Use the impeller only when the pump and sealing parts are confirmed good. Choose the OEM kit when gaskets, seals, keys, O-rings, wear plates, cups, or housings should be replaced together.

Can Marisol Marine help confirm fitment?

Yes. Send the engine brand, model, serial number, pump model, photos, and any existing part numbers to the Marisol Parts Desk before ordering if fitment is uncertain.
