Our Serpentine Pulley Upgrade Kits at a Glance
Permanent Solution to Belt Dust: ElectroMaax Serpentine Pulley Upgrade Kits provide are a lasting solution to belt dust buildup on boat engines, and suitable for a wide range of brands including Yanmar, Volvo, Nanni, and many more.
Increased Alternator Output: These kits allow for a substantial increase in alternator output without risking damage to the engine or electrical system, promoting optimal engine load during idle.
Compatibility with High-Output Alternators: Designed to work in conjunction with ElectroMaax High-Output Marine Alternators, ranging from 100 to 250 amps.
Wide Range of Engine Compatibility: Kits are developed for most Yanmar marine engines from the mid-1970s to current models and include a tensioning-arm for easy belt tensioning. Kits for other popular marine engines are also available or in development.
Amperage Increase and Fuel Savings: The upgrade can nearly triple your alternator's amperage, reducing fuel consumption by 60%, leading to significant savings and a quick return on investment.
Extended Vessel Range: By reducing fuel consumption, the Serpentine Pulley Kits significantly increase the cruising range of the boat, allowing longer stays in remote locations.
Enhanced Performance and Durability: The serpentine 10-rib belt offers smooth operation and better traction, while the machined 6061 aluminum structure and corrosion-resistant anodizing ensure strength and longevity.

Serpentine Pulley Upgrade Kits are a permanent solution to belt dust buildup on your boat engine. Pulley Upgrade Kits available for Yanmar, Volvo, Nanni, Perkins, Westerbeke, Universal and more!
Finally there’s a permanent solution to belt dust buildup on your engine and more importantly you can now substantially increase the output of your alternator without the fear of damaging your engine or electrical system – quite the contrary – you can now put the required load on your engine, when charging at idle, when on the hook.
ElectroMaax pulley kits are used in conjunction with our High-Output Marine Alternators ranging from 100 to 250 amps.

Most Name Brand Alternators Fit
We have developed Serpentine (multi grooved) Pulley Upgrade Kits for most Yanmar marine engines from the mid 1970s and all current models. In addition, we have also developed a tensioning-arm for all JH, GM, QM and YM Yanmar series engines and most Nanni marine engines. This simple device makes tensing the belt easy, no need for screw drivers or large wooden sticks to help position the alternator and can be purchased separately. Kits for other popular brands of marine engines are either available or are currently under development.
How will these serpentine pulleys benefit you?
Firstly you will eliminate the build up of fine belt dust that penetrates vulnerable engine and electronic components. NOW you are able to drive a high output alternator that actually allows you to run the engine at idle as it (the alternator) creates load that keeps the engine in good fettle without damage to the engine. If you have the space you can also add a second alternator to further enhance your engine life. Click here to watch a brief customer testimonial on our serpentine pulley kits.
Nearly Triple Your Amperage!
While a gallon of diesel at a marina is now $5.00 dollars plus, if you reduce this by 60% when running the engine to charge the batteries, what will you save? Most of our customers say it paid for itself within months, more importantly the piece of mind it gave them was priceless.
Increases the vessels range
Our Serpentine Pulley Kits increase the vessel's rangeFor those of us who cruise, the reduction of fuel consumption has a more significant value than just financial savings, it dramatically increases the range of our boat which keeps us cruising longer and allows us to stay in pristine spots when other cruisers have to leave due to refueling.
What do you think that belt dust is?
Well it’s your single-V-belt disintegrating due to slippage, why do you think the auto industry switched to serpentine 30 plus years ago?
Eventually the belt snaps (never on the dock) normally at sea when the engines hot and the sea is rough. The end result could be serious damage to your engines systems. Industrial 10 groove serpentine belts do not slip, and consequently they do not wear, and one belt will typically last the life of the engine so you typically will never need to buy a new one!
Your current single-V-belt concentrates the tension in one small area on the pulley, which stresses the bearings, the serpentine spreads the stress over three times this area running smoother (without belt slippage ) and quieter which helps to further preserve the life of your engine.
ElectroMaax optimum charging solutions are designed and manufactured in Canada with top-quality materials.
We use a serpentine 10-rib belt ( as in all automotive vehicles) in place of the single-V belt or double-V, for improved performance and reliability:
Wide serpentine 10-rib belt – Smooth, better traction for improved output
Machined 6061 aluminum structure – Light and strong
Anodized type II – corrosion prevention
Grade 8 and 10.9 zinc plated flange head bolts and nuts– quality and function
