Could be better
3 Stars
Could be better
The motor flush works, however, where the water hose connects could be better. A heavy contractor garden hose adds additional strain and can kink the flush unit or pull the hose adapter completely out. I added a hose clamp to prevent the hose adapter from pulling out. In all the unit works better than the less expensive motor flush units where water only comes in from one side.

I have an older design which Ive used for years, frankly not made as well as this one. The arms are made of a good quality spring steel which keep the ears gripped on the lower unit. This is made well so I expect it will be used for many years to come. You have to flush your outboard or inboard every time you use it. Even fresh water will cause corrosion.

Worked great! Was able to rotate muffs & hose hookup for perfect fit. While engine was not running, water was leaking past of course but once I started engine there was no leakage. This was important because I was also using this with an Antifreeze winterizer kit and didn't want to waste antifreeze.

Solid construction and worked like a charm! I was going to go mid range in pricing but am glad I went with the low priced model. Its only function is to shoot water into the lower gills and it does that fine with no leakage from connection. Big recommend!

It works! Easy to use. Do not be misled by dropping water from underneath, as soon as thermostat open its valve there is no more leak as water is running through engine.

4.0 out of 5 stars Excellent value for $15
Reviewed in Canada on August 2, 2019

Disclaimer: I haven't actually used it yet but did test fit it on mercury alpha one. I will update review after full test.

From what I can tell the build quality is very good and is almost excellent. The main hose connection seems questionable but the rest of the connections, clamps and connector hoses are top quality. If the main connection fails it would be hard to repair.

The main spring seemed to take memory a little too easily but it did hold very strong on my alpha one.

I think this earmuff will work extremely well and it only cost about $14 which is awesome value. I will be doing a full test soon and will post an update.
