Discoverd a blown head gasket on 1994 90hp sport jet, changed and backed up to the water. test fired for 1.5 seconds, fired right up. shut down imediately. backed her into the water and cranked away. No fire at all to a three leads. checked switch to ground and stator to rectifer still no fire. Stator ohms are at 725 whish is a little high per cdi book. Is it possible the pack blew in that instant or should I be looking elswere. tried later have a weeak spark to #2,#3 should it be a crisp spark?
