The kits convert your Yanmar engine's belt system to a serpentine design with 10-groove (J10) pulleys and belts, supporting higher alternator loads (up to 200A or more, depending on the alternator). Benefits include better grip and load transfer for efficient charging, lower noise and vibration during motoring, reduced belt slippage or dusting, and longer belt life compared to single V-belts. They are patented for easy installation without major engine modifications and are optimized for marine environments to prevent corrosion.
