Time to change the plugs and I'm getting two different suggestions for the plugs for my Mercury 115HP 4 stroke. Some say use the cooler 6A and some
the hotter 5A. My use is 50% trolling and 50% WOT if calm and little less if choppy. I don't think this really makes much difference, right?

If they look really,really white (hot) go with a colder plug...if they look normal run the same plug.. plugs in a marine motor
