I recently purchased a 1998 Johnson 115 FastStrike (J115GLECM). It runs fine, and the previous owner said he had no problems with it. I pulled the spark plugs today for the first time and found that the plugs in the two starboard starboard cylinders look much different than the plugs from the two port side cylinders. I have attached a pic for reference. The plugs from the starboard side have darker ceramic and a light colored ground. The port side plugs have white ceramic and "normal" looking grounds. There's obviously something different between the two sides. What should I be concerned about/looking for? Thanks for the help.
