The Mercury Racing OEM Crescent Leading Edge (CLE) Gearcase Flusher (Part #848703A1) is a high-performance engine flushing solution engineered specifically for Mercury Racing CLE lower units. Proudly made in the USA, this OEM flusher is also fully compatible with Bob’s Machine Shop nose cone gearcases and a wide range of low-water pickup gearcases from major manufacturers.

 

Precision-molded to fit securely around the crescent-shaped lower water pickups, the 848703A1 flusher connects directly to any standard garden hose. Its patented design delivers maximum water flow to ensure efficient and thorough flushing of your outboard’s cooling system—removing salt, sand, and debris buildup that can lead to overheating, impeller wear, and internal corrosion.

 

Constructed from durable, flexible polyurethane, the flusher resists cracking, rotting, and scratching for long-term reliability. The integrated elastic securing cord makes for easy, one-person installation and ensures a tight, leak-free seal every time. This makes routine maintenance fast and straightforward, whether you're flushing after saltwater use or freshwater runs.

 

Engineered with one of the industry’s largest water intakes, this flusher provides superior cooling capacity during flushing cycles, helping maintain optimal engine temperature and prolong overall motor life. It’s the most effective way to protect your high-performance gearcase investment.

To prevent impeller damage during flushing, always run the engine at idle speed only—never rev the engine while using a flush attachment.

 

Optimize the performance and longevity of your Mercury Racing CLE gearcase with the trusted, high-flow OEM flushing solution designed for professional-grade reliability.

 

This product includes one (1) Mercury Racing CLE and Bob’s Nose Coned Gearcase Flusher and is available under Part Number: 848703A1.

 

Ensure maximum cooling efficiency and extended engine life by making this high-performance gearcase flusher part of your regular maintenance routine.
