Don’t waste your time looking for a good one in the Daytona - Saint Auggie corridor, they all suck. There’s one - and I really mean one - who’s any good, his name is Chris Brown in Ormond Beach, and he’s great if you can get him. He’s usually so busy because everybody knows that everybody else around here sucks, that it’s like a 4+ month lead time whenever something breaks. If you run the boat up to Jacksonville all of the major marinas, Huckins, Lambs, etc., have qualified diesel mechanics on staff and you’ll have no issues getting service. Daytona/Palm Coast is really something else with boat repairs, I could tell you a bunch of hair raising stories.
Edited to add - there’s one other who really knows his stuff named Ken Ruse, the reason I didn’t mention him before is I heard he had a heart attack and it was unclear if he was taking any jobs. PM me I don’t think you’re allowed to put people’s numbers on here, I’ll give you both their numbers. Be prepared for long lead times on both though. Crazy times we’re living in, courtesy of the pandemic a dying sport just became popular again and it’s really starting to show.
