Find the Right Part Faster

Search by Brand, Part Number, Serial Number, Engine Model, or Service Job

Exact part numbers are best. If you do not have the number, search by brand and system, such as Yamaha water pump kit, Honda fuel filter, Tohatsu impeller, Hino belt, Sierra gasket, Volvo Penta sensor, or MerCruiser thermostat.

Parts Desk Support

Confirm Fitment Before the Boat Is Apart

Factory-authorized and brand-specific parts often look similar across engines and model years. The Parts Desk can help narrow the right path when you have a serial number, model plate photo, old part number, clear part photos, and the service job you are planning.

01

Serial Number Matters

Engine and drive model names alone are not always enough. Serial number and production range help confirm the right part.

02

Use Exact Details

Old part numbers, model plates, labels, casting marks, connector styles, and clear photos are useful fitment clues.

03

Plan the Full Job

Service jobs often need gaskets, seals, fluids, hardware, clamps, or installation parts along with the main component.

What to Send for Help

Better Details Help Us Find Better Matches

When you need help, send the engine or drive brand, serial number, model, horsepower, old part number, photos of the part and label, and a short note about the repair or maintenance job.

Factory Authorized Parts FAQ

Choosing Factory Authorized Marine Parts

What information do I need to order factory-authorized or OEM marine parts?

Use the engine, drive, generator, or equipment brand, model, serial number, horsepower, current part number, and photos of the part, model plate, or label.

Why do serial numbers matter?

Marine engines and drives can change during production. Serial number, model year, cooling setup, drive model, and installed equipment help confirm the correct part.

Can the Parts Desk help when I do not know the part number?

Yes. Send clear photos, serial numbers, model details, the old part, and the service job. The Parts Desk can help narrow the correct search path.

Are factory parts and replacement service parts always interchangeable?

No. Similar-looking parts can have different threads, seals, electrical connectors, ratings, sizes, or calibration. Confirm compatibility before ordering.
