I have a 232 with twin 200's.
Granted, it isn't as maneuverable as an inboard rig, but it can be spun around and you can back it into a slip with reasonable control if there isn't a lot of wind and current.
Tilt the engines up to the "shallow water running position." I mean trim it up to where the lower unit loses contact with the trim cylinders. Stop there and then practice backing the boat stern-to into a slip, or wherever. The prop wash is directed down and it doesn't hit the transom, giving you more thrust, therefore more control.
Try to always bring it in with engines only and the helm centered, unless there is too much crosswind. Then, you just can't do it, so at that point, use the wheel and treat it like a single engine rig.
Personally, I try not to mix the two options. Backing in with the engines AND using the wheel throw me off. One action undoes the other and I get caddywhompus in a hurry.
Practice with it. You'll get there and feel good when you slip it in stern-to with just the engines. It'll do it...
