Servicing your Yanmar 2YM15
Parts commonly replaced during maintenance include:
- Oil and fuel filters
- Seawater-pump impellers
- Alternator and pump belts
- Air filters and anodes
- Gaskets and seals
- Service kits
For larger repairs, you’ll also find circulation pumps, seawater-pump parts, thermostats, sensors, exhaust elbows, starter motors and engine mounts.
Our range includes genuine Yanmar parts and good aftermarket alternatives. The manufacturer and condition are shown on each product page.
Check the cooling system
A worn impeller, blocked seawater intake or damaged pump part can reduce the flow of cooling water and cause the engine to overheat. Inspect the impeller regularly and check the rest of the
engine cooling system if the exhaust-water flow becomes weaker.
It is also sensible to check the condition of the belts, hoses and clamps while servicing the engine.
Check the part number
Some 2YM15 parts are also used on the 3YM20 or 3YM30, but not every YM part is interchangeable. Compare the original Yanmar part number with the information on the product page 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 us identify the correct replacement.
