[QUOTE="JMichael, post: 358795, member: 7544"] Based on that serial #, the motor is a 1977. The bottom pic is too blurry to be able to tell anything, and a close up of the shaft end would help, I don't see the damage on the shaft that I would expect to see if it were slipping. Depending on what gear you have it in, it will click and the shaft will not rotate when the prop is rotated in one direction, but rotate the prop in the opposite direction and the shaft should rotate with no clicking.
