Tohatsu MSF20C Spark Problem

[Jim Mulcahey]

I have a 2011 Tohatsu MSF20C, 20hp 4-stroke that has lost spark after sitting for a few years. I am having a hard time coming up with testing procedures and output values for the pulser coil, exciter coil, ignition coil and CD unit. Can anyone help me with the service manual pages or procedures for those tests?
Thanks

Carb model of injection? tiller or remote? I have a 30 hp. Same year. Is similar to a mercury. Maybe yours is too. Try to find the mercury service manual. And you will find a lot more information on the mercury's.
One thing you can do is check if you have resistance over the sensors, ignition coil and clean the connections. check if the kill switch is not faulty. Also, you are in the wrong forum. Post it in the Honda/Nissan / Tohatsu .
