Service and repair parts
Common service parts for the 3YM30 include:
- Oil and fuel filters
- Seawater-pump impellers
- Drive belts
- Air filters
- Anodes and thermostats
- Gaskets and seals
- Complete service kits
You’ll also find parts for repairs to the cooling, fuel, electrical and exhaust systems. These may include seawater-pump parts, circulation pumps, fuel-feed pumps, sensors, exhaust mixing elbows and
Yanmar engine mounts.
Check the impeller and drive belt regularly, especially before the start of the boating season. Cooling problems can quickly lead to overheating, so worn hoses, leaking pump seals and a restricted exhaust elbow should not be ignored.
Parts shared with other YM engines
The 3YM30 shares some service parts with engines such as the
Yanmar 3YM20, but this does not mean that every part is interchangeable.
Differences in engine version, production date and installation can affect compatibility. Always compare the Yanmar part number before using a part listed for another YM model.
Check before ordering
Look for the complete engine designation and serial number on the engine identification plate. If possible, also check the number printed or stamped on the part you are replacing.
If you are unsure, send us the engine model, serial number and a clear photo of the old part. We’ll help you check which part you need before you order.
