Questions & Answers

Is this a genuine original part?

This is a premium quality aftermarket replacement part from Recambios Marinos, manufactured to meet or exceed original equipment (OE) standards for fitment and performance.

How do I know if it is compatible?

Please check your engine serial number. This belt fits YM series engines built after June 2004 with a serial number below E20848. If your serial number is E20848 or higher, you likely require a flat serpentine belt (128790-77580).

Why is the belt cogged?

The toothed (cogged) profile allows the belt to bend more easily around the tight radius of the alternator pulley, which reduces internal heat and prevents cracking over time compared to a standard smooth belt.
