Quicksilver Quickleen Engine and Fuel System Cleaner

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.

Since I know my boat I can say it runs better.

I use quickleen in every tank of fuel. It helps minimize carbon buildup and helps clean injectors.

ok ... I know everyone is thinking ... not another additive ... BUT ... my Mercury Outboard with 3 carbs on it wasn't running right ... even through I put gas stabilizer in it over the winter come time to use the engine it really didn't run right ... kinda rough and not full power ... so I took it to a reputable outboard mechanic and he told me he was so backed - up that he couldn't get to it for a week ... but then he told me "go buy yourself some "Quickleen engine & fuel cleaner pour it into the gas tank ... not too much gas in the tank ...and run that through the carbs for a couple of minutes ... wait about 3 hours and run the engine again ... that's what we would do anyway " He actually said that ... yes it ran a lot better ... now i run it with every tank.

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.

Our boat motor has been spitting and sputtering for the last couple seasons (Johnson 115) . It would get better as it warmed up, but someone recommended this hubby put this in and we had absolutely zero issues. The motor ran like a champ!! He has used Seafoam in the past, but it doesn’t come close to this product! Highly recommend!!

First time using this and I was impressed.

Put it in my atv. It perked right up. Grizzly 550 pulling wheelies again.Put it in my mower & truck too.
