How do I know if this V-belt fits my engine?
This belt is designed for a wide range of MerCruiser, Volvo Penta, and OMC engines. The best way to confirm fitment is to check your original part number against our cross-reference list (e.g., 57-13457T, 978457). You should also verify your specific engine model, year, and serial number in our compatibility tables above.
What are the signs that my V-belt needs to be replaced?
Common signs of a failing V-belt include visible cracks, glazing (a shiny, hardened surface), fraying edges, or loud squealing sounds from the engine bay, especially on startup or when under load. A loose or worn belt can cause poor performance of accessories like the alternator or seawater pump.
Is this the same quality as an OEM belt?
This is a high-quality aftermarket belt constructed from durable rubber with a reinforced fiber core. It is designed to meet or exceed original equipment manufacturer (OEM) specifications for performance, fit, and longevity in the marine environment.
