Thank you, Matt!
So by "raised" does that mean the rudder is completely inside of the hull and that gap disappears? That would be best because I really don't want to get stuck on a branch. I once got stuck on a 1" stick that went into a scupper hole. It was really hard to get off of it (once I even figured out what was happening). The bottom has deep mud and/or quicksand in the area where that occurred and I really didn't want to get out. Bloop!
There are also a lot of rocks where I work and the bottom of my Oasis is pretty scarred up after just a year on this hull. (It's my second hull.) I guess I'm also worried about damaging that transducer cover and creating a leak. I guess I'll have to go to the dealer and examine it first hand. Maybe I can make a replacement cover, myself.
