So was running fine then shut off at full throttle all of sudden took cowl off everything looked alright no spark though so went to dock via tow and trolling motor. Disconnected the black yellow wire from ignition switch still no spark. Took home checked spark at motor by disconnecting red plug and jumping batt. Positive to 3/8th terminal had spark so replaced ignition key assembly. Now had spark for about 15 mins of trying to figure out why motor was running but not right the. No spark again removed plug at motor jumped power again and have spark disconnect black yellow kill wire at ignition switch try again no spark. Does this mean wire harness has short somewhere from ignition switch to red plug at motor. Thanks in advance for any help I am confused and frustrated with things now also have spare parts motor and have changed all elec. at motor

What electrical parts did you change ?? Yes, sounds like a short in the harness.
