Quicksilver O/B & I/O Cooling/Water Pumps

Quicksilver O/B & I/O Cooling and Water Pumps: OEM Reliability for Your Marine Engine

When it comes to keeping your outboard or sterndrive engine running at a safe operating temperature, few names carry the weight of Quicksilver. As the parts and accessories brand of Mercury Marine, Quicksilver water pumps and cooling repair kits are engineered to the same factory specifications as the original components found on your engine — not reverse-engineered imitations, but genuine OEM-quality solutions built by the same company behind Mercury, MerCruiser, and Mariner power.

Why the Water Pump Is the Heartbeat of Your Cooling System

Marine engines rely entirely on raw-water cooling to survive the demands of operation on the water. The impeller at the center of the water pump draws cold water from outside the hull and circulates it through the engine to prevent destructive overheating. Over time, outboard and I/O cooling water pumps degrade — impeller vanes become stiff, brittle, or cracked, especially after a season of disuse or exposure to sustained heat. Without timely replacement, a failed impeller can lead to catastrophic engine damage that dwarfs the cost of a simple pump service.

What Quicksilver Offers in the Cooling & Water Pump Category

Quicksilver's lineup of cooling system products covers a wide range of Mercury and Mariner outboard applications as well as MerCruiser sterndrive systems. Key product types include:

• Water Pump Impeller Repair Kits — Comprehensive kits such as the 47-8M0100526 covering select Mercury F40–60 4-stroke and Bigfoot/Command Thrust outboards, 75–115 hp 4-stroke and 2-cycle outboards, and 4- and 6-cylinder Verado 135–400 hp outboards. These kits are designed to deliver higher cooling water flow rates to protect the engine.
• Water Pump Upper Repair Kits — Products like the 96148Q8 serve Mercury and Mariner 65 hp (4-cylinder) through V-6 outboards with short-vane impellers, and also fit MerCruiser I, R, MR, and Alpha One stern drives.
• Seawater Pump Body/Impeller Kits — Units such as the 46-807151A14 are specifically engineered for MerCruiser engines with engine-mounted seawater pump systems, providing a straightforward path to restoring factory cooling performance.
• Sterndrive & Inboard Kits — Quicksilver sterndrive water pump repair kits are built to contain everything needed to restore a worn or damaged pump, engineered specifically for durability and optimized cooling flow on I/O applications.
• Verado-Specific Kits — Products like the 8M0113799 target 135–200 hp 4-cylinder Mercury Verado outboards, while the 8M0104229 is engineered for V-6 and V-8 powered MerCruiser stern drives.

The Quicksilver Difference: OEM Quality, Broader Availability

Quicksilver parts are manufactured by Mercury Marine and meet the same OEM specifications as Mercury-labeled components. The critical distinction is accessibility — while Mercury-branded parts are sold exclusively through authorized dealerships, Quicksilver products are available through a much wider retail network, making it easier for DIY boaters and independent marine technicians to source the exact part they need without delay. Every Quicksilver water pump kit is designed to restore cooling function to factory specifications, giving boaters confidence that their engine is protected on every outing.

Whether you're servicing a small 6 hp carbureted two-stroke, a mid-range 4-stroke outboard, or a high-output MerCruiser sterndrive, Quicksilver's O/B & I/O cooling and water pump kits provide the right fit and the right performance.
