keeps the engine running great
I have used this for the last two years on my 40hp mercury motor and it works well and I have seen a real improvement over the past years before I started using it.

Very good luck with this product resolving issues!
I have used this product two seasons to treat the engine for build up and had good results where some engine sputtering or bad gas issues were either causing full throttle power issues or sputtering. In both instances refreshing the fuel and using this product I was able to get back to the engine running at full throttle with no issues. I change the fuel filter regularly and do use a marine treatment for ethanol however I think intermittent use of this product helps with carbeurator issues IMHO.

Helped my Volvo Penta
My boat engine seemed sluggish, I couldn't reach the top speed I used to, and it was using a little oil. My mechanic said the rings can get gummed up from sitting thorough the winter and recommended this. Initially I didn't notice a difference but partway into the second tank of treated gas it was like the engine had a good burp and started running like it should. Now I run a tank with this at the start of every season and have to more trouble.

It Works
Got rid of carbon, and my 1996 150hp 2stroke Merc runs and idles much smoother
