" The plugs on my 1975 15Hp Ev
" The plugs on my 1975 15Hp Evinrude keep fouling. At first my mixture was too rich. I have purchased a measuring device so I am sure the mix is correct. I replaced the plugs, took the boat out and when I got back the plugs were fouled.
I also discovered that the plugs installed were not what the manufacturer recommends. Would the incorrect plug cause fouling? Also, anything else I should be looking for in order to prevent fouling? "
