V-Belt – Fits MerCruiser, Volvo Penta, OMC 4.3L, 5.0L, 5.7L, 7.4L, 8.2L Engines

This high-quality V-belt is engineered for a wide range of MerCruiser, Volvo Penta, and OMC sterndrive engines. It serves as a critical component for driving engine accessories, most commonly the seawater pump and/or alternator on various V6 and V8 models manufactured between 1981 and 1997.

Designed as a direct replacement part, this belt cross-references with multiple OEM numbers to ensure broad compatibility. It is constructed from durable rubber with a reinforced fiber core to provide reliable performance and longevity in the harsh marine environment.

  • Primary Function: Powers the seawater pump and/or alternator, depending on the specific engine model and configuration.
  • Durable Construction: Made from high-grade rubber with a reinforced fiber core to resist stretching, heat, and wear.
  • Direct Fitment: Replaces specific OEM parts, ensuring proper fit and function without modification.

Installation Guide

  1. Safety First: Ensure the engine is completely cool and turned off. Disconnect the negative battery terminal to prevent accidental starting.
  2. Note the Routing: Before removal, carefully observe and take a photo of the existing belt's path around all pulleys (crankshaft, alternator, seawater pump, power steering, etc.).
  3. Release Tension: Locate the tensioner pulley or the accessory used for tensioning (often the alternator). Loosen the pivot and adjusting bolts to release the tension on the old belt.
  4. Remove Old Belt: Carefully slide the old V-belt off all the pulleys.
  5. Inspect Pulleys: Spin each pulley by hand. They should spin freely and quietly. Check for any wobble, roughness, or signs of damage on the V-grooves.
  6. Install New Belt: Route the new V-belt following the path you noted earlier. Ensure it is properly seated in the grooves of each pulley.
  7. Apply Tension: Using a pry bar or appropriate tool, gently apply pressure to the alternator (or tensioner) to tighten the belt. While holding tension, tighten the adjusting bolt first, then the pivot bolt.
  8. Check Tension: The belt is properly tensioned when you can press down on its longest span and it deflects about 1/2 inch. Do not overtighten, as this can damage bearings.
  9. Final Check: Reconnect the battery terminal. Start the engine for 15-30 seconds to confirm the belt is tracking correctly and not making unusual noises.

Troubleshooting & FAQ

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.
