QUALITY OF PRODUCT

MECHANIC IN A CAN

I’ve owned a 2006 Yamaha F90 Tiller on a Lund18 ProV since new! I Did not think there was anything wrong with my Yamaha Tiller. I had about 6 gallons left in my tank when I added the Seafoam Marine Pro. I took it to the lake, took off down the lake not really expecting a lot but boy did I get a surprise after a while the motor was running smoother, the hole shot is noticeably improved! I did not realize my motor was ill! I It was like having a Mechanic in a can. Wow this stuff works! I will use Seafoam Marine Pro with every fill up as well as winter storage!

SEA FOAM MARINE – MAGIC POTION

I have a 2014 Tracker Wt 16 w/ 60HP Mercury I purchased new . I have about 100 hrs on this and have used additives from time to time. After using Sea Foam Marine PRO for a month now my Mercury starts on the first turn of the key. It has totally cleaned out the injectors and has no spitting or sputtering. The hole shot take off has improved with no hesitation. When I idle down it will be so quiet that I have to look behind me to see if we’re even moving, it runs that smooth. I have to refuel before the next outing and I will definitely add another can of Sea Foam Marine PRO to the fuel tank. Thank you for such a great reliable product.
