2-5/8 Crank Pulley Belt Guide

The Jones Racing Products 2-5/8 Crank Pulley Belt Guide (Part No. BG-6108-A) is a precision-engineered aluminum component designed to maintain proper belt alignment and tension on high-performance marine engine pulley systems. Built from black anodized aluminum with a 1/16-inch thickness, this belt guide delivers reliable pulley management in demanding saltwater and freshwater environments where consistent engine performance is non-negotiable.

The 2-5/8-inch pulley diameter specification matches OEM applications on popular marine powerplants, while the 1-1/8-inch mounting hole accommodates standard fastening patterns. The black anodized finish provides corrosion resistance critical for boats operating in salt air and spray conditions. At just 0.03 pounds, the compact 3.1 x 1.1 x 4.15-inch footprint integrates seamlessly into tight engine compartments without adding weight or bulk. This is the kind of component where proper fitment prevents belt slip, reduces accessory drive wear, and maintains charging and cooling system efficiency under sustained throttle conditions.

Anglers and boaters performing routine engine maintenance or addressing belt wear issues will find this Jones Racing Products guide essential for restoring factory pulley geometry and belt tracking. Weekend fishermen running twin outboards and serious offshore operators maintaining larger inboard systems both depend on dependable belt drive components to keep fuel pumps, water pumps, and alternators functioning throughout a full day on the water. Sold individually, this belt guide pairs with serpentine belt kits and pulley assemblies for complete accessory drive restoration.
