The Balmar 604-150-K6 is a high-output marine alternator from Balmar's proven 604 Series, delivering 150 amps at 12 volts to meet the demanding charging needs of cruising sailboats, powerboats, and commercial vessels. Built for serious offshore and liveaboard applications, this alternator provides the robust output necessary to replenish large battery banks quickly and efficiently.
Featuring a 4-inch J-180-style saddle mount (dual foot) configuration, this alternator is a direct fit for a wide range of marine diesel engines commonly found aboard cruising and commercial vessels. The K6 serpentine pulley ensures compatibility with modern serpentine belt drive systems for smooth, reliable power transfer.
An isolated ground design is standard, which is essential for marine environments to prevent stray current corrosion — a critical feature for protecting underwater metals on your vessel.
