Newbie here. I have 85 HP Johnson with power trim. Old rig. 1975. Yesterday when I came in and trailered, I noticed the motor came up a lot farther than it usually does when I trim it up. Then when I tried to lower it again into the brace rod, it only lowered a couple of inches. It acts like it is hitting a 'stop' or something, but I can't find any stops or latches anywhere. Motors are running and they raise/lower it a few inches just fine. So someone please tell me what dumb thing I am missing or have done wrong. Thanks!
