I would like to see if I could clean the internals of my LT-1 as far as removing carbon deposits using Sea Foam. Currently I just add it, or something similar, to the fuel tank. I have looked at several videos on how it is done on a car, but didn't really see any with a boat. I would assume it would be the same procedure by sucking it in through a vacuum tube but I do not know which tube that would be. Has anyone done this before on their boat? I do not want to add it to the oil until the end of the season when it is time for an oil change again.
