I recently had both skegs repaired, the dealer had dropped the boat on the slip when installing the engines and the skegs were missing about 1 1/2 inches from each. Cost £300 for both skegs to be ground down, new skegs welded and the gearboxes resprayed. Now looks good as new.
I'm guessing that if it is only twisted you could maybe put some heat into it before trying to straighten it. Or for £150 get the skeg replaced.
