outback ls muffler

just got back from a week trip to dale hollow lake.had my 2003 ls in the water about 5 minutes when i had to pull it back out because the port side muffler had cracked at the end causing a pretty major water leak! took it a local boat repair facility who repaired the muffler with a fiberglass repair for 129 dollars.i figured it was better than waiting 3-4 days for a new muffler when i only had a 1 week vacation.anxious to see how my local dealer is going to take care of me after this dilemma.
