ElectroMaax Serpentine Pulley Upgrade Kits are a permanent solution to belt dust buildup on boat engines, and this kit covers a wide range of Yanmar marine engines. Swapping to a serpentine (multi-grooved) pulley setup lets you run a higher-output alternator without risking damage to the engine or electrical system.

Key Benefits

The kit is designed to work with ElectroMaax High-Output Marine Alternators ranging from 100 to 250 amps. Upgrading can nearly triple your alternator's amperage output and reduce fuel consumption by up to 60%, which extends cruising range and shortens the payback period on the upgrade.

The serpentine 10-rib belt runs smoother and grips better than a V-belt, and the pulley structure is machined from 6061 aluminum with corrosion-resistant anodizing for long-term durability in a marine environment.

Compatibility

This kit is developed for most Yanmar marine engines from the mid-1970s through current models, and includes a tensioning-arm for easy belt tensioning. ElectroMaax also offers a separate tensioning-arm for all JH, GM, QM, and YM Yanmar series engines and most Nanni marine engines. Kits for other marine engine brands are available or in development.
