Went out fishing other day and after using my Fortrex 101 trolling motor for about 30 minutes, it started sparking and smoking from under the foot peddle. I needed to briefly use it to get out of my location so I just pulsed it quickly while puffs of smoke continued wafting out. Will I need to replace the whole peddle or what. Has anybody had this happen? Is this a costly and or difficult fix. Motor is about 8-9 years old.
