You may have a electrolysis corrosion issue.
If the boat is at a marina/dock, there may be stray electrical current in the water that is leading to advanced corrosion.
Take photos of the tab, the corrosion and the entire side of the transom.
Contact Whaler Technical Support as well as the trim tab manufacturer. Don't talk to a dealer sales person.
