holy crap! ya, that wouldn't be any good...lol I will let him know.
Just wanted to update everyone in case anyone runs into this situation.
My dad was told by the Tracker mechanics here that they CAN install the ulterra on the classic tracker XL. They basically said they would pull the old one, fill the mount holes from the old one and put on the new bracket for the ulterra. He is pretty happy about it.
He is also getting a Lowrance HDS 9 Live for the front of the boat. I was making fun of him cause the accessories is like 1/2 the price of his boat..lol
Side note: The boat cover that comes with the tracker does NOT fit with the ulterra. So, we have to get that figured out now!
