    • Too small
The media could not be loaded. I have a 1967 Mercury 6hp and it doesn’t fit on the cavitation plate but if you put one side of the flusher on the cavitation plate it does still work.

    • Had to modify to work with Nissan 6HP
Only gave 4 stars because I had to modify it to work with Nissan 6hp. Was a simple modification, just notched out enough material so it would slide over the water intake below fin. Way easier now to flush motor using it instead of a bucket and or the flush fitting.

    • Caveat Emptor....
It could work for you but it depends. 1) For small outboards, 6hp and less, it hardly stays in place as it's too wide. even minor water pressure and the thing moves around (could use clamps to keep in place but what's the point...?) 2). it's fine if you're flushing a motor on land, and the motor is sitting perfectly vertical....but if you're at a dock and want to run and properly flush...forget about it... 3) leaks terribly. not at the hose but along the cavitation plate. 4) as others noted most outboards don't have a cav plate that's perfectly flat along bottom as the intake filter protrudes slightly below. so you need to modify via dremel.. but that will result in more leakage...so it's just a poor hack job. 5) might work better on larger outboards or those with thicker cavitation plates. for tohatsu doesn't work ... show more

    • If it fits seems like it would work.
Was able to slip it onto my 2014 Mercury 5hp 4 stroke one side at a time, however, there’s no way to avoid it coming into contact with the propeller when it spins so won’t work for this motor. Will return. Too bad, was hopeful I could be done with the bucket of water.

I gota admit I was skeptical at first based on the reviews but this simple piece of plastic does what it needs to do so far...I read several reviews complaining about getting it attached- its easy I just lube it up with a detergent(Boatwash to exact) and it slides right on with a little wiggle, the detergent doubles as ...well a detergent ... show more

    • Surprised
I actually did not think this would work, but it did! May take a little fidgeting to fit over pick up, but it worked well once in place. It would have been nice to have a rubber gasket to seal up a little better, but leakage was minimal. Sturdy.

    • It works
It fits on my 15hp mercury. It works fine, better than using a barrel or trash can ever time. It is all plastic though.

    • Easier than using a barrel full of fresh water!
Fits my 15HP Mercury 2-stroke outboard perfectly. Before I bought this I was attaching the motor to the lip on a plastic 55 gallon drum with about 40 gallons of fresh water. This was a lot of effort and wasted water. Since the motor is often used in salt water it is important to flush it with clean water after use. I have to remove the prop to use the flusher but it is smart to do this anyway as a safety procedure. I do have some concerns about the item durability but could still use the main part with spring clamps if the tabs should break off. Only time and use will tell. Right now I am just happy to be able to flush the motor easily. ... show more
