Balmar Alternator Vortec Internal Reg K6 Serpentine Pulley - 170A - 12V

The Balmar Alternator Vortec Internal Reg K6 Serpentine Pulley – 170A – 12V is a high-output marine charging solution engineered for serious boaters and anglers who demand reliable electrical power during long days on the water. Built by Balmar, a leader in marine electrical systems, this 170-amp alternator is purpose-built to handle the relentless demands of modern marine electronics—GPS plotters, fish finders, radar, and auxiliary systems—without voltage sag or charging lag.

This alternator features Balmar's proven internal regulator design, which maintains tight voltage control and eliminates external wiring complexity. The serpentine pulley configuration allows seamless integration with standard marine engine belt systems, while the 170-amp capacity delivers sustained charging performance even under full load conditions. Internal regulation provides faster voltage ramp-up and more stable output than external regulators, meaning your batteries charge faster and your electronics operate more reliably.

This unit is ideal for 12V DC systems on recreational and fishing boats, particularly those with inboard marine engines, where extended time at anchor or running multiple electronics is common. Whether you're running a tournament fishing boat or a cruiser equipped with heavy-duty electronics, this alternator ensures your battery bank stays charged and your systems stay operational.
