I've got a 96 Johnson OceanPro, It has been about five months since I last run it so I was going to start it up today just to run some fresh gas through it. Primed it, Turned battery on and turned key for about 10 sec and noticed thick white smoke comming from the top. Quickly turned key and battery off and pulled the cover off and it continued to have thick white smoke from the top for a couple of min. By the time I got the plastic covers off the top no more smoke and was not even warm to the touch. it did have a heavy burnt electrical smell to it. Any suggestions on where to start with this?
