OK got a 96 Johnson 150 (not a faststrike & see my sig for details)
I saw several posts on the plugs and if I understand correctly I should use the 78's.
What ill effect would the 82's have? That is what has been in my boat since I obtained it a little over a year ago. They were installed by a dealer...... about 2 months before I bought the boat. They haven't had much run time but wanted to know what the deal was with the 82's. Anything I will notice moving them back down to a 78?
