Dual Water Feed Boat Motor Flusher Rectangular Cup Muffs with Hose Fittings Flush Kit - Marine Outboard Engine Flushing

Used a big plastic barrel for engine testing, this clamp was so practical and easy to use, love it.

Works well. Used it for the first time last weekend. Fits snug and pushed the water through my v6 mercury 150 as you would want need and expect.

This unit is outstanding. I have an old runabout at my Minnesota lake place that I’ve always performed my own service on. The boat still looks and runs like new. Unfortunately I somehow misplaced my old motor flusher while cleaning out a shed over the winter, so was in need of a new one. You never really know what the quality is when you buy online until you get your hands on it. This product exceeded my expectations in every way. Cost a few bucks more than some of the cheapies but I guarantee it’s the last one you’ll buy (unless you lose it!) Sturdy, well made from obviously good quality materials, and worked flawlessly. A very nice unit👌

Perfect - did the job exactly as it was supposed to on the boat motor. Will recommend to other boaters as the one to get.

Works very well ! My previous one was always caused overheating alarm!
