The Balmar 60 Series Alternator Kit is the premier high-output charging solution designed for marine engines requiring a 3.15″ dual foot (Hitachi style) mount. This kit provides a complete, integrated “smart” system that maximizes battery health, decreases engine run time, and ensures your vessel has consistent power for large house banks and heavy electronic loads.
The Complete Charging System
A high-output alternator requires intelligent management to reach its full potential without overheating or damaging your batteries. This kit includes all the essential components for a professional-grade installation:
- Balmar 60-Series High-Output Alternator: A heavy-duty “small case” alternator featuring an isolated ground and dual internal fans for superior cooling and performance.
- MC-618 or MC-624 Digital Regulator: The “brains” of the system. These multi-stage regulators monitor your batteries to provide the exact voltage they need at every stage of the charge cycle (Bulk, Absorption, and Float).
- Alternator & Battery Temperature Sensors: Critical safety components that allow the regulator to automatically reduce output if the alternator gets too hot or stop charging if the battery reaches dangerous temperatures.
- Wiring Harnesses: High-quality, marine-grade harnesses with built-in fusing to simplify installation and ensure secure electrical connections.
Why Choose the 60 Series Kit?
- Universal Hitachi Style Compatibility: Designed for engines requiring a 3.15″ (80mm) dual foot saddle mount. This is the most common mounting style in the marine industry, making the 60 Series a direct high-power upgrade for Yanmar, Beta Marine, and many other diesel engines.
- Lithium (LiFePO4) Ready: The included MC-618 or MC-624 regulators feature a dedicated Lithium charging profile. Combined with the temperature sensors, they provide the precise control and safety safeguards required to charge modern Lithium banks safely and efficiently.
- Built-In Redundancy: While external regulation is recommended for peak performance, every 60 Series alternator includes an internal backup regulator. This acts as a crucial fail-safe for cruising boaters—if your external system ever develops a fault, you can switch to the internal regulator to keep your batteries charging.

Installation Notes
- Belt Selection: The 100A model can be used with a single deep-vee belt. However, for 120A and 24V 70A models or heavy-duty cycles, we strongly recommend a dual-vee or Balmar AltMount® Serpentine Conversion Kit to handle the increased mechanical load and prevent belt slippage.
