Quicksilver Idler Pulley for MerCruiser Serpentine Belt Engine Parts & Accessories

The Quicksilver idler pulley is a replacement serpentine belt pulley for MerCruiser engines. It guides and keeps tension on the accessory drive belt. This helps the belt stay properly routed and keeps the alternator, water pump and other belt-driven accessories turning reliably. Quicksilver is the genuine parts and accessories brand of Mercury Marine, so the pulley is built to work with MerCruiser engine systems.

Key Features:

• Helps maintain correct belt alignment and tension
• Made to Quicksilver and Mercury Marine quality standards for marine use
