Possibly, although I'd guess there is no more than a couple of litres absolute maximum (probably far less) in most medium sized outboards. So you are diluting 2 litres in a half a 45galon drum call it 20 galons = 90litres.
At a guess that means you are less likely to get big obstructions in the engine and as long as there is some water flowing past the obstruction it will re-disolve any residues next time you use it...
I'd have thought the ideal was to run it up to heat in the barrel and the muff it briefly while the stat is open.
