The TX sticker should always be toward the rear of the boat. On the port side (right side facing forward) when applying the numbers looking at it should read, TX sticker, TX 1234 AA the starboard (left side facing forward) side should read TX 1234 AA, TX sticker. Make sure there are spaces between the TX and numbers and the numbers and two letters. I have included a link that should help you out.
http://www.boat-ed.com/tx/handbook/register.htm Don't take it out without the numbers on there, your temp registration is only good for 3 to 4 weeks. Don't ask me how I know, but I do know...LOL The GW let me boat anyway! She was a hardA$$ at first, but lightened up after a little conversation. Just gotta show respect for the law!
Also, make sure you have your registration card on the boat! I did have mine, and she checked it!
See ya on the water,
