Quicksilver Power Steering Oil Cooler

The Quicksilver 8M0125855 Power Steering Oil Cooler is a genuine OEM replacement component engineered specifically for MerCruiser sterndrive power steering systems. Designed to maintain proper fluid temperatures under demanding marine operating conditions, this cooler helps protect power steering components and ensure reliable, responsive steering performance on the water.

Measuring 11.50 inches (292 mm) in overall length and featuring 1.25 inch (32 mm) O.D. hose fittings, this unit is a direct-fit solution for a broad range of MCM sterndrive engines powered by GM in-line 4-cylinder, V-6, and V-8 powerplants. It supersedes the original part number 861544T — while the hose outlet orientation differs from the original, the cooler performs identically in service. This part also replaces Mercury and Quicksilver part numbers 861554T01 and 807292T.

As a genuine Quicksilver factory OEM part, this cooler meets Mercury Marine's exacting standards for quality and durability. Always confirm fitment using your engine serial number before ordering, as photos and descriptions may vary.
