I have my Dad's old 70 Mercury 7.5 horse. It stopped running just after getting in the water and I noticed the wire fell out of what I believe to be the coil for the top cylinder. Part number says 336-3955. Is this a coil assembly? Has the short plug wire in it for top plug and two bolts inset into the top in some kind of resin. Kindof a dummy when it comes to outboards, trying to get this thing back in the water to catch some crappie!
