Read the reviews - This Stuff Works!
Our 75hp Mercury outboard hadn't been run for a over a year. Prior to that it just didn't seem to have the power it should & also sounded like it had bit of an intermittent miss. I read through some boating forums and saw the high praises for this product as being better than the Marine Seafoam. It is made by Mercury so figured I didn't have much to lose and everything to gain. On the recommendation to "shock" the system and clean the fuel system and de-carbon the power head properly, I used a 3oz. to one gallon ratio. I had a small portable 3 gal. fuel tank and once on the lake I switched over from the onboard boat fuel tank to the portable. Almost instantaneously I could tell/feel the difference with the motor....seriously, scouts honor! I continued to run out the small tank varying throttle positions at times. When done with the "shock treatment" the motor was back to running smooth & powerful as it should. Made our fishing trip in MN a pure joy. I'm a firm believer now and will always use this additive as directed for sustained maintenance whenever fueling up. PS....don't forget to add a quality fuel stabilizer as this product does not contain those pertinent ingredients. Fish on.

Its awesome
The best by far of any cleaner I've seen. Seafood is very good stuff and a favorite go to when in a bind, but this cleaner is 10 times better

Husbands things
My husband bought this. I don’t know much about it but he has zero complaints. He bought it for a boat. He has fixed up 2 boats, sold one & we kept the other. So he apparently knows what to buy & how to use it.

my Mercury outboard runs great
any one who has an outboard motor knows the frustration of keeping it running smoothly and the costs for taking into the shop. I bought this quickleen when my motor kept cutting out on me while trolling. I have used it all season this year and my Mercury outboard has never run better no hesitation, or stalls every since I've been using it. I just add it every other fill up or so along with the fuel stabilizer and no problem. It's a little pricy but a lot cheaper than taking into the shop.
