Good, Simple, Inexpensive
Works great for hooking up a hose to my 1996 Evinrude 25 hp outboard for running the motor to make sure everything's OK before launching in the spring. I run in fresh water so there's no need to flush at the end of the season. The unit does not seal perfectly, but it doesn't need to - just has to get enough water to the water pump to lubricate the pump and keep the motor cool, which it does.

Works perfect
Had bought a set from Walmart that just didn’t quite fit my motor shape but these were perfect ! Cheaper then Walmarts and fit/work much better.

Great product! I bought this as a stocking stuffer for my husband. His old one had moving parts that made it difficult to use. This also caused him to drop it in the water a couple of times. Thank goodness we live on a shallow canal and we were able to retrieve it. The Sea Dog is wonderfully constructed and easy to use. We highly recommend this product.

Sea Dog Motor Flush - Simple but works!
Simple design but works. Use this on 95 60hp Johnson on my 95 Aqua Patio Pontoon. Have only used is a couple of times but the Sea Dog motor flush holds on & does not move, covers the intakes completely & engine pulls water well. Ran the engine for several minutes and I don't think the Sea Dog moved at all despite all the water and vibrations. So far so good.

I wouldn't buy anything else this work great!! It fits tight enough so you can get plenty of water going through your motor. Before this I bought one at Wal-Mart that I paid more money for it was a rectangle shape no water would come out of the tall tail, I ended replacing the water pump, then very hot water would come out it hurt to tough it. I ended up taking it to the shop and the mechanic told that I might be using the wrong motor flush. Sure enough I was, he recommended this one or even one just like it and now it flushes great...no problems!!

good product
works as advertised, seems to be good quality, no issues to report. however, while you are using it remember that vibrations from the motor can shake it off without you realizing it. good to zip tie it on or use some other method to ensure you don't kill your motor.
