i took out my 90hp force for a run and it ran fine for about a hour, When we slowed down the engine the motor stalled. There was no spark, but when we pushed the throttle fully ahead and held the nutetral switch open the motor had spark and the motor would start and the boat would run until we slowed the throttle down again. I'am told that the stator has a high and low winding. Any information you could provide would be greatly appreciated.
