Balmar 120A 12V Dual Foot K6 Isolated Ground Alternator

The Balmar 60 Series Alternator puts out 120 amps at 12 volts. It runs through a 3.15-inch dual foot saddle mount with a single K6 serpentine pulley, sized for engines that already run that mounting footprint.

Isolated ground construction keeps the alternator's case electrically separate from the engine block. That separation reduces stray current paths that can cause corrosion or interference issues elsewhere on the boat's electrical system.

It uses Hitachi-style mounting, typical for Yanmar, Westerbeke, Lehman, and Perkins-Sabre engines. It's worth confirming the engine brand matches before ordering. Explore more marine alternators.
