Mercury – Water Pump Base | Cooling System | Reinforced Nylon | 96146A6

Overview

When you run a V-175 Mercury outboard, you get used to the steady hum of a strong, confident engine. It’s a sound you trust—whether you’re skimming across glass-still morning water or pushing home through a late-day chop. But that calm, consistent performance depends heavily on one thing: a cooling system you can count on. The Quicksilver 96146A6 Water Pump Base helps restore that dependability by giving your outboard a solid foundation for proper water flow. It’s a small part with a big influence on engine health, and having a fresh one installed brings real peace of mind every time you drop the boat in the water.

Key Features

• Provides a stable base for water pump impeller operation
• Constructed from durable reinforced nylon for long-lasting performance
• Integrated seal ensures tight, secure fitment
• Meets or exceeds Mercury OEM specifications
• Includes water pump base with molded-in sealing surface

Engine & Boat Compatibility

This water pump base is specifically designed for:

• Mercury V-175 outboards
• Commonly used on bass boats, deep-V hulls, center consoles, ski boats, and performance fishing rigs

If you’re running a V-175 two-stroke and want factory-matched cooling reliability, this is the correct component.

Performance & Practical Benefits

When the water pump base wears, cracks, or stops sealing properly, the symptoms show up fast—sluggish cooling, uneven temperatures, surging idle, or that uneasy feeling when the tell-tale stream isn’t as strong as it should be. Replacing the base with the Quicksilver 96146A6 brings everything back into balance.

Here’s what you’ll feel on the water:

• Smooth, steady cooling flow thanks to a firm, perfectly aligned pump foundation
• A tight, secure fit that reduces the risk of air leaks or incomplete priming
• More consistent operating temperatures during long idle zones, heavy loads, or high-speed runs
• Reliable protection for internal components like cylinders, seals, and water jackets
• Easier installation thanks to its precise, OEM-matched shape and integrated seal

It’s the kind of upgrade that instantly improves your confidence in the engine—because your cooling system is only as strong as the base holding it together.

Why Buy OEM

A water pump base isn’t something to gamble on. Choosing a Mercury OEM part means:

• You’re getting the exact fit and material strength engineered for your V-175
• Reinforced nylon provides durability that aftermarket plastics often lack
• The integrated seal is shaped to Mercury’s factory tolerances
• You can install it once and trust it for seasons to come
• It protects your investment by keeping the cooling system performing the way Mercury intended

When you’re miles from the ramp, that kind of reliability isn’t optional—it’s essential.
