Perhaps a silly question but...are there supposed to be washers & nuts on the inside of all 4 slidemaster jack plate bolts? I have them on the side with the talon mounted to it but none on the other side. Ashamed to say I never noticed it before. Am looking to raise the motor for the first time and picked up on it. Want to make sure all is in order before I do anything. Thx in advance for any insight.
