The Vetus Serpentine Pulley Kit from ElectroMaax replaces the factory alternator pulley with a multi-groove serpentine design, ending the belt dust that comes with a high-output alternator upgrade. It's built to pair with ElectroMaax High-Output Marine Alternators from 100 to 250 amps.
A 10-rib serpentine belt provides smoother operation and better traction than a standard V-belt, and a tensioning arm is included to make belt adjustment easy without extra tools. The pulley is machined from 6061 aluminum with corrosion-resistant anodizing for long-term durability.
Moving to a higher-output alternator with this kit can substantially increase your amperage output and cut fuel consumption compared to a stock setup, extending the range you can cruise between fuel stops.
This kit fits Vetus M3.10, M4.14, and M4.17 engines. Kits for other engine brands and models are available separately.
