This high-output alternator delivers reliable, high-amperage charging to keep your auxiliary battery banks topped up. Featuring a 3.15in (Approx. 80mm) Hitachi-style dual-foot saddle mount, it is a high-performance upgrade for engines with this mounting style, typical for Yanmar, Westerbeke, Lehman and Perkins-Sabre engines.\u003c\/p\u003e\n\n\u003ch3\u003eWhy Choose an Isolated Ground Alternator?\u003c\/h3\u003e\n\u003cp\u003eStandard automotive alternators use the engine block and chassis as the electrical return path. In marine vessels and specialised composite-body vehicles, this can lead to severe galvanic corrosion, stray current issues, and interference with sensitive onboard electronics. This 60 Series unit features a dedicated \u003cstrong\u003eIsolated Ground (IsoGrd)\u003c\/strong\u003e terminal. By isolating the negative return path from the alternator case and engine block, it significantly reduces the risk of stray current corrosion on hulls, propellers, and underwater metal fittings, whilst providing a cleaner, more stable electrical circuit for your charging system.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features and Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Output 120A Charging:\u003c\/strong\u003e Provides substantial current at 12V to rapidly replenish deep-cycle house batteries, supporting high-draw appliances such as inverters, refrigeration, and navigation systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIsolated Ground Architecture:\u003c\/strong\u003e Protects marine vessels and specialised vehicles from galvanic corrosion and stray electrical currents.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3.15in (Approx. 80mm) Saddle Mount:\u003c\/strong\u003e Hitachi-style dual-foot mount, typical for Yanmar, Westerbeke, Lehman and Perkins-Sabre engines.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCustomisable Drive Setup (No Pulley Included):\u003c\/strong\u003e Supplied bare to allow precise matching with your engine's existing belt profile, preventing belt slip and premature wear.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Fan Cooling:\u003c\/strong\u003e Compact, small-case 6-Series design with dual fan cooling and a high airflow frame.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCustomise Your Belt Drive: Compatible Pulley Options\u003c\/h3\u003e\n\u003cp\u003ePlease note that this alternator is \u003cstrong\u003esupplied without a pulley\u003c\/strong\u003e. High-output alternators place increased mechanical load on engine drive belts.

Standard factory alternators quickly derate as engine bay temperatures rise, resulting in slow charge times. Balmar designs its 6-Series alternators for recreational applications and describes them as ideal for modest charging upgrades. Its Smart Ready internal regulator may be sufficient where battery loads are relatively small and the engine runs frequently. For larger deep-cycle battery banks, or where the engine runs less often (as on most sailing vessels), pair it with a Balmar ARS-5 or Max Charge multi-stage regulator.\u003c\/p\u003e\n\n\u003ch3\u003eReady to Upgrade Your Charging System?\u003c\/h3\u003e\n\u003cp\u003eConfigure your ideal marine or mobile charging solution today.
