View Full Version : Sears Diehard Trolling Motor

Need a prop for this old Sears Diehard electric trolling motor. Can’t find a model number but after some “googling”, I’m fairly certain that it is a 488585100. Prop no longer supplied by Sears. Called sears, no information provided that would facilitate finding a replacement. Anybody know if this was possibly made by Minn Kota or motorguide for Sears?

Update: found the model number 488-588610 serial# 230990, 1 HP, shaft measures about 1/4 inch ( about 6mm) and has a plastic wingnut, motor measures 2.5 inches (about 63 mm) in diameter, and old prop measures 2 and 7/16 inch (about 61 mm) in diameter. Anybody know a good place to look for a replacement on-line. Unable to find one locally…thanks!

Update #2: sounds like it was made by minn Kota, 2 versions of prop were available, MKP-1 and MKP-5. Both listed as obsolete or out of stock everywhere I have looked. Anyone know if they will cross reference with an aftermarket part?
