Yanmar alternator upgrades

Yanmar 3JH4. 4JH4, 3HJ3, 4JH3, & 3GM30 Serpentine Conversion Kit


This serpentine pulley and belt conversion kit is designed to fit the *Yanmar 3JH4, 4JH4 3JH3, 4JH3 & 3GM30 marine engines*, using our "Aquamaax"line of Saddle Mount alternators 80amp thru 190amp.

Boat owners are now no longer limited to upgrading their old alternator to a 100amp alternator on a single V pulley with this kit you can now increase the output up to 190amps if required.

Electromaax's serpentine conversion kits are designed and manufactured to replaces the conventional narrow single-V belt with a serpentine 10-rib belt, increasing performance and reducing vibration.

 


Yanmar Serpentine Conversion Kit Features:

  • Wide serpentine 10-rib belt – Smooth (large improvement over dual V-belt, including reduced harmonic vibration), better traction for improved output and less tension required.
  • Anodized 6061 machined aluminum parts, providing exact fit and tolerances – corrosion prevention and lightweight.
  • High grade steel (grade 8 and class 10.9) nuts, bolts, plated for corrosion prevention
