Like Zim said, v/direct drives are a different beast at low speeds. Spend some time practicing the throttle bump. Two useful moves are the sidewalk and pirouette.
For the sidewalk, at a dead stop, turn the wheel all the way to the right (starboard), then alternately bump the throttle forward and reverse. The nose will push to starboard in forward, and the stern will pull starboard in reverse. With a little practice on the timing, you can "walk" the boat sideways to starboard.
To turn around in tight spaces, it's best to concede that you're gonna turn left (port), and perform a pirouette. Again from a dead stop, but turn the wheel all the way left and alternately bump the throttle forward/reverse. With patience, it'll look like you're spinning the boat on the ski pylon.
Good luck, she's a real beaut!
