Description
The Yanmar 25132-004600 is a genuine OEM V-belt for Yanmar 4JH, 3JH and 6PHM series marine diesel engines, where it drives the engine accessories.
Why it matters
The V-belt drives the engine accessories, and on many installations the seawater pump, so losing it can mean losing engine cooling. Carry a spare.
Fitting
Inspect the belt at every service and before long trips, and replace it if you see cracking, glazing or missing material. Check the tension and pulley alignment at the same time.
Check your fitment
The engine models listed in the product specifications are a guide only. Always confirm against the parts catalogue for your engine’s model and serial number before ordering. If you are unsure, send us your engine plate details and we will check it for you.
