Howdy Ya’ll, 
   I just got in a 1970 Johnson 25hp. And immediately I noticed a cool feature that this motor had. There is a U-shaped pin that rests in the top tilt pin holes. You put the tilt lever to release and raise the motor and rest it on this u shaped pin. Then move the lever to lock and it locks onto the pin. My question is, was this something someone fabbed up?  I don’t see this pin anywhere in the parts diagrams.  I’ll try to get a pic of it posted in here.  Thanks in advance
