Balmar 100A 12V Single Foot Dual Vee Isolated Ground Alt

The Balmar 621 Series Alternator puts out 100 amps at 12 volts. It runs through a 1-2 inch single foot spindle mount with a dual deep vee pulley, the lower-output option in this mounting family for boats that don't need the full 120A version.

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.

The 1-inch Motorola-style mounting fits Westerbeke, Lehman, Hino, and Pathfinder engines. The 2-inch Delco-style mounting covers Volvo Penta, John Deere, Perkins, Mercruiser, Pleasurecraft, Crusader, Indmar, and other GM-based engines. Check out the rest of our marine alternators.
