I currently have a motorguide 12/24 trolling motor with a 36 " shaft and gator mount. I am looking a buying a new motorguide trolling motor but the minimum shaft length for 12/24 is 45 " and there are 3 wires. The current motor has a 4 prong plug. Does a gator mount hold a 45" shaft and can I hook a 3 wire motor to a 4 prong plug. also it looks as though the recessed foot pedal is a different design. Hopefully the new foot pedal fits into the current recess box.
