Check your engine and part number
The 2YM15, 3YM20 and 3YM30 are different engines, even though some service parts are shared. Differences can also occur between production versions.
Check the complete engine model and serial number on the identification plate. Compare the original Yanmar part number whenever possible.
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 check it before you order.
