Balmar Alternator 100 AMP 12V 3.15" Dual Foot Saddle K6 Pulley w/Isolated Ground

The Balmar Alternator 100 AMP 12V 3.15" Dual Foot Saddle K6 Pulley with Isolated Ground is a marine-grade electrical generation system engineered for heavy-duty maritime power delivery. Built for offshore and extended-range vessel operations, this 100-ampere unit provides the sustained electrical output required by multi-system marine engines operating in demanding salt-water and high-load environments.

Rated at 100 amps in 12-volt configuration, the unit features a 3.15-inch pulley diameter optimized for serpentine belt systems and dual-foot saddle mounting that anchors securely to engine blocks across Yanmar, Westerbeke, Lehman, and Perkins-Sabre platforms. The isolated ground design eliminates stray current pathways that typically corrode immersed metal structures, extending service life in harsh saltwater conditions. The K6 serpentine pulley accepts standard multi-groove belts, simplifying field replacement and maintenance logistics when operating far from service infrastructure.

This alternator is specified for operators of trawlers, research vessels, offshore support craft, and extended-range cruising sailboats where onboard power redundancy and electrical system reliability directly impact mission continuity and crew safety. The Hitachi-style mounting architecture ensures drop-in compatibility with existing engine installations, reducing downtime during service intervals. Replacement for the legacy 60-100-SR-IG model, this unit maintains backward compatibility while delivering proven performance across commercial marine fleets.
