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.

Maybe it works! Maybe it doesn't!!!
I dunno if it really did anything for my 150hp merc jet drive, I surely didn't notice any difference in starting/running/getting up on plane, but maybe I just have a good engine that doesn't need any additive stuff for it! Really, I just bought this more for preventative maintenance and wasn't really expecting any miracle of more power or anything. She starts up just fine like she normally does, and 40mph for a 150hp jet is pretty good as it is (the fiber reeds helped a lot with top end and take off). I'll use it up over the next several months and if I notice any real difference, I'll update this come spring '21.

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.
