Servicing your 2GM or 2GM20
Parts commonly replaced during servicing include:
- Oil and fuel filters
- Seawater-pump impellers
- Drive belts
- Air filters and anodes
- Gaskets and seals
- Service and repair kits
For larger jobs, you’ll also find circulation pumps, seawater-pump parts, fuel injectors, exhaust elbows, starter motors, alternators and
Yanmar engine mounts.
Our range includes genuine Yanmar parts and good aftermarket alternatives. The manufacturer and condition are shown on each product page.
Check the complete engine model
The 2GM family includes versions such as the 2GM, 2GMF, 2GM20, 2GM20F, 2GM20V, 2GM20VE, 2GM20FV and 2GM20FVE.
Parts can differ between raw-water-cooled and freshwater-cooled engines. A part for a 2GM20F will therefore not necessarily fit a standard 2GM20.
Check the complete model designation on the engine plate and compare the original part number before ordering. If you’re unsure, send us the engine model, serial number and any number shown on the old part. A clear photo can help too.
