Currently my 2010 2520xl has the 12x12 trim tabs in a pocket under the stern. I guess my question is. I am thinking of extending the current tabs instead of removing and replacing. My thoughts are to widen the tabs by 4" on each side and extend the tabs by 6". It won't just be a 20" by 6" plate I was going to make it 20" wide by 10" square then cut 12" out of the center deep enough to allow 4" of the new plate to extend along the edges of the existing tab for more welding strength. Anyway, was wondering if anyone has tried this and how it might have worked. Can't see at least not trying it before deciding to remove existing then filling pocket buying new and reinstall. If it works it would be a quick and easy fix. Basic tabs have 144 sq inches. After make over they should have around 270 to 275 sq inches. Any thoughts?
