I towed my 4500 pound boat weekly to the lake, but drove two blocks only and never went on a public road to get to it. I could also do wheelies on the speed bumps, but we won't go there. Bottom line is that a 2500 pound boat should have a tongue weight of 250 pounds, so a HD class 3 receiver should work for you, provided you were not going to tow the boat for 500 miles. Check the owner's manual for the maximum towing capacity for certain.
