Re: Mercury 9.8 hp weak spark

Before going out a buying a stator assembly, start checking each component out throughly. Is the resistance the same on both coils? Are the plug wires and ends unbroken and free of corrosion(and the wiring from the pickup coils) Are the points gapped and timed correctly?… You know peice by piece, one step at a time. I highly doubt your stator is bad as they are bulletproof ,however…

John <br />That model has 2 white plastic insulating blocks that the points wire goes through at the bolt.<br />These crack and can be very hard to see the cracks.(shows up more like carbon tracks)<br />The voltage will track to ground from these, I would advise you to replace these anyway.<br />Have seen alot of guys change stators and the only problem was the blocks.
