Thorough Diagnostic Assessment
No guesswork. We meticulously track down battery drains, GFI faults, fuel flow restrictions, and mechanical gremlins to solve root causes.
Honest & Clear Communication
JT keeps you updated from start to finish with fair pricing, straightforward explanations, and zero hidden surprises.
Mobile Dockside & Weekend Priority
From our Sebastian base to your private dock, ramp, or marina in Vero Beach, mobile service is ready when you need it most.
"JT at Blackwater Marine in Sebastian was outstanding. He spent the time to properly assess the problem so the job would be done right the first time, instead of rushing to a quick fix. He was available to us on the weekend and made us a priority, which meant a lot when we were stuck. We were having issues with both the port and starboard batteries on our inboard Meridian, and we were trying to figure out whether a failed GFI switch might have had something to do with the drain, or whether it was an unrelated problem. JT took that seriously and worked through it with us carefully. I would highly recommend JT and Blackwater Marine to any boater who wants honest, thorough work."
