How much Sea Foam for my boat motor? [SOLVED]

I added Sea Foam to a plastic tank with about 5 gallons of premix (2 cycle out board, 115 hp). I will add 10 gallons of fuel before taking it to the lake. Are there any issues with that use?

Hi Lee. It seems you added one can of Sea Foam to what will amount to 15 gallons of boat fuel. That will work as a maintenance dosage. For cleaning, you can add a lot of Sea Foam to fuel – the more you add, the better and faster it cleans! One way to use a higher cleaning concentration would be to just use the 5 gallons and run the motor without having to add the 10 gallons.  Using the 5 gallons would be a 3 ounces per gallon cleaning ratio. Hope this makes sense!
