    no spark situation

    I have a no spark situation on my 1997 ski nautique With a 351 Ford PCM engine. I was just sitting at idle after boat was done pulling skiers and she just shut down, like you turned the key off. First I checked the kill switch, OK. then cap and rotor, OK, still no spark. I had 12 volts at the pos. side of the coil with the ignition switch in the on position. I swapped the coil, still no spark.
    I'm thinking maybe the module in the distributor??? Please help

      Has anyone replaced the electronic ignition spark module in a 1997 ski nautique with a 351 Windsor engine and the prestolight distributor W/ the screw down cap. Looking for some guidance ....

          I have not but since no one else is jumping in this is what I found when asking AI about it. It would appear this is a somewhat common failure depending on hours and in line with what you're experiencing. It would also appear that there could be several other possible issues that could have the same symptoms as you describe. There is a YouTube video that is referenced that gave me a bit of a chill and way past what I would personally do to resolve the issue with your current system. Rather than digging as deep as they go in the video, I would be converting over to a Pertronix distributor and calling it a day. I've included both AI results and a screen shot of the Nautique Parts Pertronix distributor offering.....

          It looks like Nautique Parts is selling a Pertronix conversion as well....

              The GT40 engine of my '02 was just rebuilt. Not saying this is the problem with your boat, but a similar situation happened to us. We were skiing for the second time after the rebuild and the engine stopped from 3 mph like we shut off the key. Ends up the pin sheared that holds the gear on at the bottom of the distributor shaft. I was told it was a manufacturing defect and the distributor is being replaced since it has a lifetime warranty.
              Ski on dude!

                  If it sheared a pin like the above statement you should be able to remove the cap, hit the key and see if the rotor is turning. That would be a quick one to check.
