Trusted Service You Can Rely On

Saltwater and electricity are a tough combination, and even well-maintained boats develop wiring faults, charging problems, and corroded connections over time. At St. Pete Mobile Marine Mechanic, our technicians handle marine electrical repair alongside a full range of outboard motor repair and boat service work — all performed at your location, on your schedule. Whether your bilge pump quit overnight or your electronics went dark before a fishing trip, we diagnose the problem fast and fix it right the first time, saving you the hassle of trailering to a shop.

Why Choose Us?

  • Our marine electrical repair work is performed to ABYC standards, so every circuit, connection, and ground meets recognized safety requirements for marine environments.
  • We trace faults from the battery bank through every branch circuit on the boat, so intermittent gremlins don't get left behind after the visit.
  • Corroded terminals, chafed wiring, and moisture-damaged connectors are rebuilt with marine-grade tinned wire and heat-shrink terminals rated for saltwater exposure.
  • If a wiring fault is hiding a deeper engine or charging issue, our one-crew approach means the same technician can move straight into engine diagnostics without scheduling a second appointment.
  • We provide a free quote before any work starts, so you know the cost before we touch a single wire.

Battery and Charging System Diagnosis

A weak or failing battery is one of the most common reasons boats won't start, but the real culprit is often the alternator, voltage regulator, or corroded battery cables. We load-test batteries, check charging output at the alternator, and inspect every connection in the charging circuit. Left unchecked, a marginal charging system will strand you mid-bay.

Common Signs You Need Service

Catching an electrical fault early on a boat is far cheaper — and safer — than dealing with a fire, a flooded bilge, or a dead engine at the worst possible moment.

Lights Flickering or Dead:

Navigation or cabin lights that flicker or stop working point to corroded connections, a failing switch, or a voltage drop in the circuit — all issues that tend to get worse with time.

Fuses Blowing Repeatedly:

A fuse that keeps blowing is telling you there's a short or an overloaded circuit somewhere downstream. Replacing the fuse without finding the cause risks damaging equipment or starting a wiring fire.

Battery Won't Hold a Charge:

If your battery drains overnight or struggles to start the engine after a normal interval, the battery itself, the alternator, or a parasitic draw from a faulty device may be to blame.

Burning Smell or Discolored Wiring:

A smell of burning plastic or wires with melted or discolored insulation is an immediate red flag. Shut off the affected circuit and call a marine electrician before using the boat again.

Frequently Asked Questions

How much does marine electrical repair typically cost?

Costs vary widely depending on the fault — a simple fuse block replacement runs much less than a full rewire or a shore power isolation transformer installation. Because every boat and every problem is different, we always provide a free quote after diagnosis so you know the price before we start. Call (727) 739-0447 to schedule a visit.

Do I need a marine electrician or can I fix boat wiring myself?

Minor tasks like swapping a fuse or replacing a burned-out bulb are generally fine for a confident DIYer. However, wiring that carries AC shore power, charging circuits, or anything tied to safety systems like bilge pumps and navigation lights should be handled by a qualified marine electrician — improper work can create fire hazards or galvanic corrosion that damages the hull over time.

How long does a typical marine electrical repair take?

Simple repairs such as re-terminating corroded connections or replacing a faulty switch often take one to two hours. More involved work — like tracing an intermittent short, installing a new electronics suite, or upgrading a shore power system — can take a full day or require a follow-up visit. We'll give you a realistic time estimate when we provide your quote.

What brands of boat do you work on?

We service electrical systems on virtually any powerboat, sailboat, or yacht regardless of make. Our boat service work covers all major brands, and our technicians are comfortable with both older analog wiring setups and modern NMEA 2000 digital networks. If you're unsure whether we can help, just give us a call and describe your boat.

Can you diagnose why my boat battery keeps dying?

Absolutely. A battery that drains faster than it should is one of the most common calls we get. We check the battery's health under load, measure the alternator's charging output, and run a parasitic draw test to find any device that's pulling power when the key is off. Most causes — a faulty relay, a stuck bilge pump float switch, or a poorly wired accessory — are straightforward to fix once identified.
