Balmar 97XD Series Alternator – 190 Amp, 24V with K6 Serpentine Pulley – 97XD-24-190
The Balmar 97XD Series Alternator – 190 Amp, 24 Volt (97XD-24-190) is an extra-heavy-duty, high-output marine alternator engineered for vessels with demanding electrical loads and large 24V battery banks. Designed for continuous, high-amp output, this alternator is ideal for commercial boats, offshore cruisers, trawlers, and power yachts requiring reliable charging power under sustained operation.
Built on Balmar’s 97XD extra-duty frame, this alternator features enhanced thermal management, heavy-gauge windings, and robust internal components to support extended high-output use without overheating. The 190-amp output at 24 volts delivers exceptional charging capacity at cruising RPMs, ensuring efficient recharging of house batteries, inverters, navigation electronics, and onboard systems.
Equipped with a K6 serpentine pulley, the alternator provides improved belt grip, reduced slippage, and quieter operation compared to traditional V-belt systems. The unit is designed for use with external smart regulators, allowing advanced multi-stage charging profiles that maximize battery performance and longevity across AGM, gel, and lithium battery chemistries (with proper regulation).
Constructed with marine-grade, corrosion-resistant materials, the Balmar 97XD Series alternator is built to perform in harsh saltwater environments and is trusted by professional installers and long-range cruisers worldwide.

Crucial "Not Included" Items
Because this is a professional-grade system, there are two items required for operation that are typically sold separately:
-
External Regulator: This alternator does not have an internal regulator. You will need a Balmar MC-620 (24V) to operate the unit.
-
Temperature Sensors: To protect your investment, it is highly recommended to use the MC-TS-A (Alternator Temp Sensor) and MC-TS-B (Battery Temp Sensor) with your regulator.
Would you like me to create a "Technical Requirements" checklist? This would help your customers understand exactly which regulator and cable gauge they need to purchase alongside this alternator to avoid installation delays.
Important Installation Note: Due to the extreme power output of this unit, it requires the use of a high-quality external regulator (like the Balmar MC-620) and appropriately sized heavy-gauge cabling.
The Balmar 97XD Series Alternator – 190 Amp, 24V with K6 Serpentine Pulley – 97XD-24-190 is the perfect solution for boat owners and professionals who require maximum charging power, durability, and reliability in demanding marine electrical systems.
