More About Our Serpentine Kits

Serpentine Marine Pulley Kits
Finally a permanent solution to belt dust buildup on your engine.

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 enough load on your engine, when charging at idle, when on the hook.

Electromaax Kits are used in conjunction with our high output marine alternators ranging from 80 to 180 amps.

Most other brand alternators may also fit. We have now developed serpentine (multi grooved) kits form most Yanmar marine engine from the mid 1970s and all current models. In addition we have developed a new tensioning arm for all JH, GM and YM Yanmar series engines. This simple device makes tensioning the belt easy, no need for screw drivers or large wooden sticks to help position the alternator and can be purchased seperatly. Kits for other popular brands of marine engines are either available or are currently under development.

Electromaax optimum charging solutions are designed and manufactured in the USA 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

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.

I wanted the most bang for my buck & after talking with John at Electromaax, I liked their product & ordered a 160 amp alternator, smart regulator and serpentine pulley kit for our boat.

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 consequently they do not wear, and with a life time warranty you 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.
