Interesting challenge... From the throttle control I can move my outdrive all the day down but not all the way up. It will trim up mid way but won't come all the way up. If I lean over the back of the boat there is another switch back there and I can press it to bring the outdrive up with no problem. I'm not sure it's the switch up front because it does trim up and down, just not all the way up. Thoughts?
