• Standard 49K6 (6-groove, 49mm) Pulley
• Pulley Hardware (M17 x 1.5 x 24mm nut, w/ 18mm ID x 29mm OD washer)

Key Benefits & Specifications:

• High Power Output: Provides a maximum cold output of 5.7kW PTO (3,960 Watts / 144 Amps at 9,000 RPM) and sustained cruising output of 5.1kW PTO (3,575 Watts / 130 Amps at 6,000 RPM) for ample power in any condition.
• Low Turn-On (LTO) Capability: Begins generating power at just 1,072 alternator RPM, producing over 1.4kW (51 Amps) at under 1,500 RPM and nearly 2.4kW (87 Amps) at 2,000 RPM, ensuring robust charging even at low engine idle speeds.
• Superior Cooling Performance: Features dual cooling fans, heat-shedding E-coat finish, and an exterior-mounted rectifier, allowing it to run significantly cooler than competitors for increased durability and sustained amperage output.
• Native 24V Rotor Design: Unlike competitors that use less efficient 12V rotors, the Zeus alternator utilizes a true 24V rotor and field current for optimized performance, efficiency, and extended lifespan.
• Isolated Ground: Ensures enhanced safety and compatibility, protecting sensitive marine electronics from common ground interference.
• Compact & Lightweight: Weighs only 15.89 lbs (7.2 kg), offering more power in a smaller, lighter package compared to older designs.
• Versatile Mounting: Designed to replace most domestic alternator styles using a standard 1" or 2" single mounting foot.
• Certified Quality: SAE J1171 certified, meeting rigorous marine ignition protection standards.
