Hopefully you did not heat the screw, but the surrounding area. The key to heating is to use alot of heat quickly, not slowly. You want to heat the surronding area quickly to expand it while not heating the screw and expanding that. Try heating it again, and then you can try either the impact driver again or get the biggest screwdriver you can that fits the screw and use a wrench (if it has a hex shape on the shaft) or a large pair of vice grips or even a pipe wrench to turn the screwdriver. Make sure you are turning it the correct way (counter clockwise while looking at it) . I would try all of these methods before resorting to drilling it out.

drill it and use an "easy out". this requires you to drill a hole ( read the instructions) into the center of the offending screw/bolt. Then you take an easy out, which is basically a hardened screw with reverse threads on it and place it into the whole, the tapered threads on the easy out will go in a little ways and then make contact with the stuck screw. continued pressure with a large wrench in a counter clockwise direction will cause the easyout to continue to bite into the screw until you reach enough force to get it to come out. I have on a few occasions broken off an easy out, it is rare, but can happen so be aware. If that fails, your gonna have to drill out the entire stuck screw and threads, then retap it to a larger size and install a new larger screw. Just be sure to use a a drill and easy out that contacts the inside of the stuck screw, and not the threaded hole itself.
Good luck

Drilling can be dangerous. If your bit drifts into the aluminum it will only take a second to do serious damage to your gearcase. I would take it to a machine shop. Spend 50 bucks instead of 1500.

The impact driver is usually my weapon of last resort, although you may want to try heating it up with a blowtorch (so long as nothing nearby will be affected by the heat) - but just get it hot, don't melt it or warp it. Otherwise, drill it out completely and re-tap the hole for a bigger screw next time, or use a heli-coil (thread replacement.)
Good luck!

This is a pain. You may call a welding Shop and just ask if he can get it out. Some have done this for people where I live. IF, you get this thing out, put some Anti-Seize on it and maybe it not stick next time.

sounds like you will have to drill it out and retap.

get it really hot but don't melt the aluminum case
