I have an 87 Evinrude 115 hp on an 87 Bayliner Cobra 1700 runabout and all the sudden when we're out I could only get 3100 rpm at about 10 mph, I checked the coil packs and they are firing but I am puzzled at what it could be. Help, ideas please.
I have a 1985 Evinrude 115 hp, I have fire at all plugs but in the water I top out at 2200 rpms. When I check the plugs, the one on the top/right plug is smoked up and oily, like it's not firing. But out of the water all 4 plugs are firing. Please help. Thank you!
