Went out last Wednesday and when we were coming in the motor sputtered once or twice. Changed plugs Saturday thinking that is what it was. On Sunday we were fishing a tournament and started out ok still a little miss. After our morning run the boat would take about 300 to 400 yards to get up on pad and was missing terribly. What do ya'll think. Motor is 1989 evinrude XP 150. Boat is 1989 Ranger 364V
