I wanted to fog the engine to winterize it and I can't find them, the manual doesnt show them? I just got the boat in april this year. Thanks for help, Happy Thanksgiving..

Look for 4 separate wires that are going into the sides . Remove the cover. I will email you a photo of my motor to help. Happy gobble gobble.
