Serial Number Matters
Engine and drive model names alone are not always enough. Serial number and production range help confirm the right part.
Use Exact Details
Old part numbers, model plates, labels, casting marks, connector styles, and clear photos are useful fitment clues.
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.
