Performance & Real-World Benefits

The 43026T2 impeller helps keep your engine running at its best by maintaining consistent water flow. Its flexible vanes create an even seal inside the housing, pushing water efficiently through your cooling system at all speeds. That means stable temperatures, steady oil pressure, and peace of mind when you’re miles from the dock.

If you’ve noticed your telltale stream getting weak or your engine running warmer than usual, it’s time for a new impeller. This OEM replacement restores the cooling system to full performance and helps protect your motor from heat damage.

Why Choose Mercury OEM

The Quicksilver 43026T2 is a genuine Mercury Marine impeller, engineered specifically for your outboard or sterndrive. Cheaper aftermarket versions may look the same but often use inferior rubber compounds or incorrect blade geometry, leading to poor water flow and short service life.

Mercury’s OEM parts are built and tested to handle the extreme heat and RPM demands of marine engines. With OEM, you know it fits right, performs as intended, and lasts — no guesswork needed.
