Shortly after greasing the motor swivel, the motor became very stiff. When I first put the grease gun on it was very hard to pump. Maybe two pumps before I moved it around then if flowed freely. I disconnected the cable to the motor to check if that was the problem. Steering wheel turned freely, motor still very hard to turn manually. It has not been in the water yet this year. The motor was turning freely before the greasing. I also had just started it on muffs and let it run no more than thirty seconds if that. Prior to doing those two things it was fine. Any thoughts? Thank you
