How do you get through the gym and fight with flannery in Pokemon ruby?

The Gym itself is a series of water chutes which you must negotiate to get to the Leader. Trainers also pop out of the watery holes, so stay on your toes. Cooltrainer Zane

Torkoal: Level 28 Most of the battle with Flannery is pretty easy... but then she reaches for Torkoal. If you don't have a strong Water-Type to face her with, watch out. Torkoal's Overheat is a hardcore move that can drop nearly any Pokémon you send out. Its Body Slam is no laughing matter, either. Be sure to have lots of Potions on hand and use them liberally. If in a pinch, use a Self-Destruct move to end this fight. When you do, you'll earn the Heat Badge and all of the prestige that comes with it, including the fact that you'll be able to control all Pokémon up to Level 50. You'll also have the ability to use Strength outside of combat, which will allow you to get a couple extra goodies on the Fiery Path, including a Fire Stone and TM06 (Toxic). Next time you walk the path, be sure to pick that stuff up. In addition to the Badge, you'll also get the powerful TM50 (Overheat). Teach it to someone you love. Once you set foot outside of the Gym, your Rival will run up to you and give you the Go-Goggles. Now you'll be able to manage the sandstorm on Route 111.
