Balmar 60-100-K6 60-Series 100 Amp 12V Dual Foot Saddle Mount Marine Alternator with K6 Serpentine Pulley

The Balmar 60-100-K6 is a high-output marine alternator from Balmar's renowned 60-Series lineup, delivering 100 amps at 12 volts to keep onboard battery banks reliably charged. Featuring a 3.15" dual foot saddle mount (Hitachi-style) and a K6 serpentine pulley, this alternator is a direct-fit solution for engines using Hitachi-style brackets, including Yanmar, Westerbeke, Lehman, and Perkins-Sabre diesels. It replaces the discontinued 60-100-SR-IG.

Built around Balmar's Smart Ready® Technology, the 60-100-K6 can operate with its internal regulator for light electrical loads, while also being fully compatible with Balmar's external multi-stage regulators — including the ARS-5 and Max Charge series — for vessels with larger deep-cycle battery banks or less frequent engine run cycles. This makes it an ideal upgrade for sailboats and powerboats that demand more from their charging systems.
