Balmar Alternator 3.15" Dual Foot Saddle Dual V Pulley Regulator & Temp Sensor - 170A Kit - 12V

The Balmar Alternator 3.15" Dual Foot Saddle Dual V Pulley Regulator & Temp Sensor — 170A Kit in 12V delivers reliable high-output charging specifically engineered for marine electrical systems. This complete alternator kit is designed to upgrade vessels that demand sustained power for navigation equipment, refrigeration, electronics, and auxiliary systems during extended offshore runs or live-aboard operations.

Balmar marine alternators incorporate high-reliability bearings, robust rectifier diodes, and optimized heat-sinking architecture to handle the thermal and electrical demands of continuous marine service. The 170-amp output rating provides substantial charging capacity to maintain battery banks under heavy electrical load, critical when running multiple systems simultaneously in offshore or cruising environments. The dual V-pulley configuration offers installation flexibility across different engine types and mount orientations, while the 3.15" saddle mounts secure the unit to the engine block without modification. The integrated voltage regulator maintains consistent output across varying engine speeds, and the temperature sensor monitors charging performance under the elevated ambient and engine-bay temperatures common on working vessels.

This kit addresses a specific gap in marine electrical infrastructure: weekend fishermen and serious cruisers frequently discover that factory alternators cannot sustain power-hungry modern systems—sonar, autopilot, electric winches, cabin heating, and communications—especially on extended trips where engine runtime is limited. The 170-amp capacity bridges that gap without requiring custom wiring or external regulation modules. Salt-air corrosion and vibration are inherent marine stressors; Balmar's component selection prioritizes durability in these conditions, making this upgrade a foundational reliability improvement for any vessel operating beyond coastal day-use patterns.
