No lubrication on actual motor. Cable might be froze up. Should be an adjustment under the pedal somewhere to tighten/loosen the cable. Not many motors out there on the lower end of product lines that are worth the money. I hate Minn Kota but run a fortrex. Its really noisy compared to my motor guide tour I use to run, but motorguide does not make a trolling motor I would buy anymore. If it stays outdoors when not used it could be froze up and need replaced. If the actual prop will not turn could be a number of problems that might cost more than you paid for the motor in the beginning.
