Power Steering Pulley Serpentine 4in

The Power Steering Pulley Serpentine 4in from Jones Racing Products is a direct-replacement component engineered for marine engines that demand reliable, consistent steering hydraulic pump operation. Whether you're running a high-performance inboard, outboard, or jet drive system, this precision pulley ensures your steering response remains crisp and predictable under heavy load. Built for boaters who spend serious time on the water, this pulley addresses the exact mechanical demands of marine power steering systems where failure can compromise both safety and control.

Constructed from aluminum and finished in black anodized coating, the Power Steering Pulley Serpentine 4in features a 4-inch diameter with a six-rib serpentine drive profile designed for efficient belt engagement and reduced slippage. The press-on design simplifies installation on compatible pump shafts, eliminating the need for special tooling on most applications. The anodized finish resists corrosion in salt-water and freshwater environments alike, critical for any marine component exposed to spray, moisture, and atmospheric conditions. At just 0.47 pounds, its lightweight construction minimizes vibration while maintaining the structural integrity necessary for years of reliable steering assist.

This pulley is ideal for anglers, cruisers, and serious boaters replacing worn or damaged steering pump drive components or upgrading to a performance-matched serpentine belt system. Compatibility depends on your specific engine platform and power steering pump design; verify fitment against your engine manufacturer's specifications and current pulley dimensions before ordering. Installation requires removing the serpentine belt and pressing the new pulley onto the pump shaft using standard mechanical equipment—a straightforward job for any experienced mechanic or DIY boater with basic marina workshop access.
