Replacement Mercury 525 / 600 / 700 Sea Pump Pulley - Grip Coated

All Hardin Marine sea pump pulleys use a mandrel on the pump, then the pulley bolts to the mandrel. Some manufacturers sell you a press-on pulley, these usually work themselves off. This version has a special grip coating on the belt surface to improved contact with the belt. This coating is metallurgically bonded textured metal coating that increases friction, reduces wear, and improves performance. Replaces OEM Mercury #899743T
