Servicing your 1GM or 1GM10
Common maintenance parts include fuel and oil 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 which engine you have
The 1GM and 1GM10 are closely related, but not every part fits both engines. Differences can also occur between versions and production years.
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 check the correct part.
