Around your area I wouldn't know. But DFW area would be Charlie's Outboards in Alvarado and if you want the absolute best in my opinion that would be Joe Mauldin in Hallsville at Town and Country Marine.
Couldn't help you in Wichita Falls but around Lake Fork J&J and Service Marine are good shops. But the best deal going is Micheal Cicino, and he even does house calls.
