HTD Belt 23.307in Long 30mm Wide

The HTD Belt 23.307in Long 30mm Wide from Jones Racing Products is a precision synchronous drive belt engineered for marine and boating engine applications where reliable power transmission is non-negotiable. If you've spent years on the water, you know that engine reliability directly impacts safety and performance—whether you're running a high-performance ski boat, a commercial fishing vessel, or a dedicated tournament platform. This HTD (High Torque Drive) belt transfers rotational force between pulleys with minimal slip, maintaining consistent accessory drive operation under the variable loads encountered in marine service.

Constructed with reinforced synthetic teeth and a 30mm width profile, this belt accommodates 8mm pitch spacing for positive meshing with matching pulley grooves—the standard that prevents creep and ensures predictable timing across charging systems, water pumps, and cooling fans. The 23.307-inch circumference fits mid-range marine engine packages, and the HTD tooth geometry distributes load more evenly than older V-belt designs, reducing wear on both belt and pulley surfaces. Weighing just 0.25 lbs, this belt delivers durability without adding measurable mass to an already optimized engine bay.

Operators replacing worn accessory drive belts on their in-board or outboard powerplants will appreciate the straightforward installation process and OEM-equivalent fit on engines originally spec'd for this exact circumference and width. Verify your current belt length and pulley pitch before ordering to ensure compatibility with your marine engine configuration. Routine belt inspection—especially after extended operating seasons—keeps your boat's electrical and cooling systems running at peak efficiency, preventing mid-water failures and extending engine longevity.
