Mercury – Water Pump Impeller | Cooling System | Elastomer Construction | 952892

Overview

On a small outboard, every sound and vibration feels personal. You hear the rhythm of the engine, feel the push of the prop, and count on that little powerhead to move you across the water without complaint. That’s why a healthy cooling system matters so much. The Mercury 952892 Water Pump Impeller brings back the confidence you expect from a well-tuned 3.3hp Mercury or Mariner outboard. It restores that steady, reliable cooling flow that keeps the engine calm, smooth, and running exactly the way it should—whether you're easing away from the shoreline or heading back in against the tide.

Key Features

• Provides essential cooling water flow to protect your outboard
• High-quality elastomer impeller blades for flexibility and long lifespan
• Bonded center insert resists tearing to help maintain consistent water flow
• Designed for durability and higher flow rates across temperature swings
• Meets Mercury Marine OEM specifications for proper fit and performance

Engine & Boat Compatibility

This OEM impeller is designed for:

• Mercury and Mariner 3.3hp 2-cycle outboards
• Ideal for dinghies, tenders, small inflatables, jon boats, portable setups, and ultralight craft
• Compatible with common transom-mount, portable outboards used for fishing, exploring, or backup propulsion

If your 3.3hp Mercury or Mariner depends on a compact but capable cooling system, this is the correct match.

Performance & Practical Benefits

A worn impeller doesn’t just reduce cooling—it changes the whole personality of the engine. You’ll hear it in the pitch, feel it in the handle, and sense the strain as temperatures creep higher than they should. Installing a fresh Quicksilver 952892 impeller brings back the tight, smooth, steady performance that small outboards are known for.

Real-world benefits include:

• Reliable, consistent cooling flow during idle, acceleration, and long runs
• Better temperature stability in warm shallows or colder early-season water
• Enhanced protection for the cylinder walls, seals, and moving components
• Reduced risk of overheating—one of the biggest enemies of small 2-stroke engines
• Easy installation with common tools, making it a straightforward maintenance job

It’s a small part with a big impact, especially if you rely on your portable outboard for everyday use or as a dependable backup.

Why Buy OEM

When it comes to impellers, precise materials and tolerances matter. Mercury OEM parts offer:

• Exact fitment with no guesswork
• Materials engineered specifically for marine cooling conditions
• Long-term reliability and smooth running
• Better value over time compared to aftermarket options that may underperform or wear quickly
• The confidence of using a part built and tested for your exact engine

This is the kind of maintenance that pays for itself with every hour you spend on the water.
