Wait... I got a 17" belt and 16" deck when I had Kongo.

Try to lower the amount of ammunition in your guns. That will help reduce weight and give you more armor. Furthermore, don't be afraid to max out your displacement. When fully loaded, Kongo can get 26 knots, which is still 2-6 knots faster than most other BBs.
