Charleston's #1 Mobile Marine Mechanic

About Poseidon Mobile Marine Mechanics

Charleston is a serious boating city. The harbor, the barrier islands, the Intracoastal Waterway, the ACE Basin, there’s no shortage of water to explore, and no shortage of reasons to keep your boat in top shape. What there often is a shortage of is reliable, qualified marine mechanics who come to you.

That’s the gap Poseidon Marine fills. Our mobile marine technicians are licensed, insured, and certified across all major inboard and outboard engine brands. They bring everything needed to diagnose and repair your vessel on-site, at your marina, your home dock, or wherever your boat is located in the Charleston area.

Getting a boat to a shop when it won’t run isn’t always possible. We get that. Our entire operation is built around coming to you, getting the job done right the first time, and getting you back on the water.
