Mobile Marine Electrical Repair in Sarasota

Boat Electrical Problems Solved at Your Dock

Electrical issues can be some of the most frustrating problems for boat owners. From dead batteries to non-working gauges, even small faults can interrupt your plans or compromise safety.


At Master Tech Marine, we provide mobile marine electrical repair throughout Sarasota and surrounding coastal areas. Our technicians bring years of experience diagnosing and fixing electrical problems on-site — no need to haul your boat or wait days for a shop appointment.


Whether you're docked at home or moored at a marina, we’ll come to you with the tools, testing equipment, and parts needed to get your systems working again.

Marine-Grade Electrical Work, Done Right

Boat electrical systems are different from those on land. Saltwater exposure, vibration, and limited space make quality work critical. Our technicians follow marine-grade wiring standards and use proper waterproof connectors, tinned copper wire, and corrosion-resistant hardware.



We focus on long-term reliability — not just temporary fixes.

Whether you're dealing with a single failing circuit or need a full wiring overhaul, we take the time to do the job properly.
