The Balmar 94LY-24-140-IG alternator was specifically designed for Yanmar 6LY diesel engines and, as a large-format 24V/140A alternator from the 94LY series, delivers exceptionally high charging performance for large house battery banks. It is designed for professional continuous operation on long-distance yachts and workboats and reliably covers demanding electrical loads in a 24V onboard electrical system.
Advantages
- Specially designed for Yanmar 6LY engines with a 3.15" dual-foot Hitachi-style mount for a perfect fit
- Extra robust windings, diodes, and carbon brushes for continuous full-load operation
- Isolated ground connections for safe 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: 24V / 140A
- Mounting: 3.15" dual-foot (Hitachi-style) — two-sided mounting specifically for Yanmar 6LY diesel engines, unlike the 2" single-foot mounting (Delco-style) of other 94 models
- Maximum Speed: 7,000 RPM
- 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 mount fits directly onto the existing brackets of these engines, eliminating the need to modify the original mounts.
Area of Application
Ideal for long-distance yachts, fishing vessels, and motor yachts with Yanmar 6LY engines and large 24V onboard electrical systems or lithium battery banks, where reliable recharging under continuous load is crucial.
As this is a high-performance professional alternator, we recommend checking the exact engine designation of your Yanmar 6LY and the belt configuration with philippi support before purchasing.
