A dependable impeller is one of those little things that keeps you boating with confidence. The Quicksilver 8M6010331 Water Pump Impeller gives your Yamaha 25hp C25 outboard the steady water flow it needs to stay cool, whether you’re easing through a no-wake zone before sunrise or pushing upriver against the tide.

Performance & Practical Benefits

A water pump impeller isn’t glamorous, but it’s absolutely essential. If it’s worn, cracked, or losing flexibility, your outboard simply can’t pull the water it needs to stay cool. The Quicksilver 8M6010331 gives you:

• Reliable cooling flow so your engine maintains steady temperature
• Smoother operation during long idle periods or slow trolling
• Improved durability thanks to premium rubber that resists swelling and fatigue
• Better performance under load, especially in warm shallows
• Longer engine life, since proper cooling prevents internal wear

When you replace an old impeller with a fresh one, you’ll feel the difference almost immediately. Your Yamaha runs more confidently. It starts cleaner. It holds its temperature on those long runs where you used to worry about heat. It’s one of the simplest ways to protect the engine you rely on every season.

Why Buy OEM

There are plenty of aftermarket impellers out there, but a cooling system is not the place to gamble. With Quicksilver you get:

• An exact match to Yamaha OEM specifications
• Proper water flow at idle and full throttle
• Long-term reliability without premature cracking
• A fit that drops into place with no modification
• The peace of mind that comes from using a part engineered for marine life

It’s affordable insurance for an engine that needs dependable cooling every time you turn the key.
