Many locals speak highly of Lester's Outboard Repair (904) 731-1277. They always seem super busy, and I have not used him, but they've been helpful over the phone. If they can't come to you, I would trust anyone they recommend.
Last year I had a bad experience with a local (Jacksonville) authorized Honda outboard sales and service dealer. They made a total hash out of my Honda BF-50. PM me and I'll tell you who to avoid.
