Dry Sump Pump Pulley

The Dry Sump Pump Pulley is a critical component for high-performance marine engines where consistent oil pressure is non-negotiable. Designed for use with Gilmer-style belt systems, this pulley ensures the external oil pump maintains the precise RPM needed to lubricate internal components during high-speed operation or heavy seas. Boaters and marine mechanics choose this specific component to replace worn pulleys or to fine-tune pump drive ratios for optimal engine health.

This 28-tooth pulley is precision-machined from high-grade aluminum to provide a lightweight yet durable solution for demanding environments. The black anodized finish offers essential corrosion resistance against salt spray and moisture, while the Gilmer tooth profile prevents belt slippage under load. Engineered for a 5/8 inch shaft, the Dry Sump Pump Pulley provides a secure fit and reliable power transfer to the oiling system.

Marine performance enthusiasts looking to buy a reliable drive component will find that the Stock Car Products 1104-28 offers the durability required for racing or offshore applications. Its specific tooth count allows for exact drive ratio calculations, ensuring the dry sump system operates within its intended performance envelope. This pulley is an essential specification for anyone building or maintaining a high-output marine engine requiring external oil scavenge and pressure stages.
