Since 2011

Our Company Message

We established Tri County Mobile Marine in 2011 to fulfill a need & desire in the Charleston Metro area that was going unnoticed and unfulfilled.  So many folks were sick and tired of having their boats locked down and out of service for 2, 4 sometimes 6 weeks at a local dealer.

We stepped forward and created a new & great experience for our local boating Clientele! We come to You! We service and repair your outboard engine & boat on site! No more hauling it in or having to find a trailer to borrow to begin the haul!
