I have a 1983 35hp Evinrude that starts with one turn of the key and runs
really good.
My problem is when I turn the ignition off the motor won't stop.
I have replaced the ignition switch and the starter solenoid but it still
won't stop when I turn the key off.
Is it possible it could be the CDI unit? Is there a way to test it?

Not sure what to do or where to look. Any help would be appreciated.

Thanks, Shane.

Outboard ignition switches have to be grounded. AT off position the ign
wire from the motor is grounded. In START and RUN the ign wire is OPEN (not
grounded). This differs from most CAR ignition systems where power is
applied to IGN to run and a disconnect =off

If the IGN wire is not connected to the switch or you have an automotive ign
switch or your ign switch is not grounded it won't turn off the engine.

Most often in outboards the engine won't start or it intermittently shuts
off because of leakage to ground from a bad switch (SALT + WATER = bad
switch).
