My outboard started to act strange...stalls, sudden death, poor idle.
i was planning to empty a can of gum out in my 6 gallon fuel tank.
Question, would running such a high concentration of gumout ruin any
components? These small little cans are made to mix with up to 21
gallons of gas.

I'd rather run this concentrated gum out fuel through the outboard (all
six gallons) to see if it clears or cleans up the problem before taking
it to the mechanic. Do the expert mechanics on this forum think it's
not a good idea? Thanks.
