Evinrude Trim Issues

[2LazyHounds]

So update 17 or whatever we're on now. After some tinkering around and adding more fluid I finally got things working. Mostly. The motor will trim all the way down but not all the way up. My boat has two trim rods and the main cylinder that is connected to the motor. It will only go as far up as the two trim rods will lift it. After that, nothing. I can manually lift the motor all the way, which is quite heavy, so I know that cylinder is not stuck. Thoughts?
