Trim Plate Operation and Movement

Hey Everyone,

New member here and just joined the Supra club on the weekend with a 2009 Sunsport 24V. As I'm getting to know the boat, I had a question around the trim plate operation. I have a single trim plate, controllable from the cockpit. It was hard to notice the difference in position when we had it out for the first time on Sunday (and I was getting a lot of cavitation at slower speeds), and so troubleshooting yesterday, I noticed it only moves maybe 1-1/2" at most. I believe it is in the full up position with only a minimal downward deflection. Was hoping someone could validate what I should be seeing (I was expecting a lot more), and maybe point out what I might look at to solve it.

Alreadly learned a bunch reading through some posts, but couldn't find anything specific to this.

Thanks for the help in advance.
