The Balmar 94LY-12-210-IG alternator, specifically designed for Yanmar 6LY diesel engines, delivers exceptionally high charging performance for large house battery banks as a large-format 12V/210A alternator from the 94LY series. It is designed for continuous professional operation on long-range yachts and workboats, reliably covering even demanding electrical loads.
Advantages
- Specifically designed for Yanmar 6LY engines with 3.15" dual-foot Hitachi-style mounting for a perfect fit
- Extra robust windings, diodes, and carbon brushes for continuous full-load operation
- Isolated Ground connections for secure integration into the onboard electrical system
- Corrosion-resistant, powder-coated surface for use in salty marine air
- Bidirectional cooling fan for reliable cooling regardless of the direction of rotation
- Meets USCG Title 33 ignition protection regulations for safe operation in the engine room
- Optional tension arm hardware kit (94LY-0050) available for clean belt tension
Technical Data & Compatibility
- Voltage/Current: 12V / 210A
- Mounting: 3.15" Dual-Foot (Hitachi-style) — two-sided mounting specifically for Yanmar 6LY diesel engines, in contrast to the 2" single-foot mounting (Delco-style) of other 94 models
- Maximum RPM: 7,000 U/min
- Pulley: Dual-Vee pulley, minimum size 1/2", Serpentine (K6/K8) optionally possible
- Certification: USCG Title 33 ignition protected
- Mandatory: external Balmar multi-stage regulator (e.g., MC-618 or MC-624, sold separately) — no internal regulator fallback available
Why specifically for Yanmar 6LY?
The 94LY series was specifically developed by Balmar for the design of the Yanmar 6LY engine family. The 3.15" dual-foot Hitachi-style mounting fits directly onto the existing brackets of these engines, eliminating the need to modify the original mounts.
Area of Application
Ideal for long-range yachts, fishing vessels, and motor yachts with Yanmar 6LY propulsion and a large 12V onboard electrical system or lithium battery bank, where reliable recharging under continuous load is crucial.
As this is a powerful professional alternator, we recommend comparing the exact engine designation of your Yanmar 6LY and the belt configuration with philippi support before purchasing.
