there are two trim dials on your outdrive. On mine, merc bravo one outdrive. The right one adjusts the position on the trim gauge. The left side adjusts the up switch limit. Your drive should not go up more then 1/4. After that you use the trailer button. Reason is the u joints start to bind as they go up. Trailer button is use with engine off.
Call me if you got any questions on adjusting. Randy 949-395-4144
