Outboard Engine Flusher Dual Feed Sterndrive Boat Flushing Hose Attachment

High flow flushing muffs, for higher horsepower outboard motors and sterndrive engines. Dual feed supplies water to both muffs at the same time. Engine manufacturers recommend your engine is flushed out with fresh water after each use. These muffs allow you to easily run your engine off a hose. Suitable for virtually all larger outboards and sterndrives. Also allows engines to be warmed up on the trailer before the boat is launched. Flushing with freshwater massively increases engine, heat exchanger and exhaust manifold life. 9cm circular muffs. 39cm total length. Suitable for larger 5/8" (16mm) diameter hose pipes.
