Yanmar

Yanmar engine and saildrive parts

Yanmar marine diesel engines include the GM, YM and JH families. Use the complete designation, such as 1GM10, 3GM30F or 3YM30AE, rather than the cylinder count alone. Suffixes and serial-number ranges matter when comparing parts. Identify an SD saildrive separately from its engine.

Service parts and repair components

Look for oil and fuel filters, impellers, belts, gaskets and cooling-system parts. When servicing an SD saildrive, identify the drive before choosing seals, anodes or other components. Before routine maintenance, compare the required service items with your engine manual.

Search by part number

Use the original Yanmar part number and compare the engine or drive model with the product details. Check serial-number restrictions and any replacement references. Across its range, MPS offers new, OEM, remanufactured and used parts; availability and condition vary by item. Read the listing to see which option is offered and what is included. Worldwide shipping is available.

Questions about choosing parts

Can I choose Yanmar parts using only GM, YM or JH?

These are engine families, not complete model references. Use the full designation and serial number, then compare the original part number with the listing.

Are 3GM30 and 3GM30F parts interchangeable?

Do not assume they are. Yanmar distinguishes these model variants in its parts catalogue. Check the complete model, cooling arrangement and applicable reference before selecting an impeller, belt or pump.

When should I replace filters and the impeller?

Use the maintenance schedule for your exact Yanmar model and operating conditions. A service interval quoted for another engine is not a substitute for your manual.
