Hmmm. Strange that 1/4" of additional toe-in would correct your handling issue. I still think you have something else going on. Did you add any weight to the vessel recently such as a tender on the platform or something very heavy in the bilge below the fish boxes? Too much weight in the stern can cause adverse handling, leaning and the inability to turn well. I would still check the shaft covers if you have not already done so.

Good Luck!
