I have a NISSAN 2 cycle, 3 cylinder, 1998, 70hp NS70C outboard I'm trying to get running. It won't rev above 3700 rpm. I've tried a shot of carburetor cleaner while running and it has no effect so I started checking the electrical system. The pulser coils are putting out the minimum acceptable value voltage but 2 cylinders are getting below minimum spark voltage and the third is getting no clear voltage. So it appears the CDI is bad. Unfortunately, this part does not seem to be available new OR used. Here's the questions. Even though the CDI isn't available, could a 3 cylinder CDI with the correct leads transplanted from the existing CDI be substituted? How can you find a suitable substitute? Any advice on how to get this engine running again would be appreciated. It has less than 100 hours on it and parting it out because of the CDI seems like such a waste.
