Servicing your 2GM or 2GM20
Common maintenance parts include oil and fuel filters, seawater-pump impellers, drive belts, anodes, gaskets and seals. We also stock thermostats, pumps, engine mounts, fuel-system parts and other components for larger repairs.
Where available, you can choose between genuine Yanmar parts and good-quality aftermarket alternatives. Complete service kits are also available when you want the main maintenance parts together.
Check your complete engine model
The 2GM range includes several versions, such as the 2GM, 2GMF, 2GM20 and 2GM20F. Parts can differ between raw-water-cooled and freshwater-cooled engines, and not every part fits every version.
Before ordering, check the complete model designation and compare the original part number where possible. If you’re unsure, send us the engine model, serial number and a photo or number from the old part. We’ll help you identify the correct part.
