Marine Electrical Repair in Long Beach and San Pedro
We diagnose and repair boat electrical systems at your slip, dock or storage yard from Marina del Rey to Newport Beach, or at our San Pedro shop. We trace the fault from the batteries to the panel, find the cause and quote the repair before any work is done.
What the work covers
The core service is marine electrical repair and troubleshooting: dead circuits, tripping breakers, corroded connections and wiring that has been added to over the years. The work also covers:
- Batteries and charging: marine battery replacement and charging system repair, plus lithium LiFePO4 battery conversions and power upgrades.
- Shore power: shore power inspection and cord replacement.
- Corrosion: electrolysis and galvanic corrosion testing, with a check of the bonding system.
- Solar: marine solar panel design and installation.
- Networks: NMEA 2000 networking and digital switching systems.
- Lighting, sound and internet: underwater LED lighting, marine audio upgrades, Starlink installation, and marine electronics installation and repair.
Parts are quoted with the job.
When to call
- Batteries that go flat overnight or will not hold a charge
- A breaker that keeps tripping, or a circuit that works one day and not the next
- A shore power plug or inlet that looks burnt or feels hot
- Zincs that wear away fast, or pitting on props and running gear
- Electronics that reset, flicker or drop off the network
Questions about marine electrical repair
Why do boat electrical problems come and go?
Salt air and moisture corrode terminals and crimped joints. A weak connection can pass a quick check and still fail when the circuit carries current, so we test circuits under load.
Is a lithium battery conversion a simple swap?
Usually not. Lithium batteries charge differently from lead-acid, so the charger, alternator and battery monitor often need changes as part of the job.
Book a visit: submit a ticket with the boat, where it is kept and which circuits are acting up, or call (562) 542-7296.

#393 Common question asks
Are marine speakers really different from car speakers?
-
Yes. Marine speakers are built for salt, UV, moisture and vibration, and to project sound in open air. Car speakers are not, and they tend to corrode or fade quickly on a boat.

#391 Common question asks
Can you upgrade my speakers and subwoofers directly at my slip?
-
Yes. We install speakers, subwoofers and amplifiers at your slip or dock anywhere from Marina del Rey to Newport Beach, or at our San Pedro shop. A trip fee by distance applies to each visit, from $30 in San Pedro to $110 in Newport Beach, with no trip fee at the shop.

#389 Common question asks
Do you install high-end marine audio systems on all types of boats?
-
We install marine audio on cruisers, center consoles, pontoon boats, sailboats and larger yachts. We check the layout, the space for speakers and amplifiers and the battery and charging capacity first, and tune each system for its zones.

#387 Common question asks
Do you handle complete Starlink setup, activation, and wiring?
-
Yes. We handle the installation, cable routing, power, network setup and onboard Wi-Fi, and we help you activate the kit on your own Starlink account. The Starlink subscription is between you and Starlink.

#385 Common question asks
How fast is Starlink on a boat compared to 4G/5G?
-
It varies with your Starlink plan, the dish, how much open sky it sees and how busy the network is, so we don't promise a number; Starlink publishes typical speeds for each plan. Near the harbor a strong 5G signal can be as fast. Offshore, where cell coverage fades, Starlink is usually the only fast option, and a Peplink router can switch between the two automatically.
-
-
#383 Common question asks
Can you integrate Starlink with my existing marine electronics?
-
Yes. We connect Starlink to your router and onboard Wi-Fi so phones, laptops, cameras and network-capable chartplotters or monitoring systems can use it. Starlink is an internet link, so it does not connect to an NMEA 2000 network directly.
-
-
#381 Common question asks
Do I need special marine mounts or can I use the stock Starlink hardware?
-
For boats, we recommend marine-grade mounts, reinforced bases, vibration isolation, and proper cable routing. Stock home mounts are not designed for marine use and can fail under wind load or saltwater exposure.

-
#379 Common question asks
Will Starlink work reliably offshore along the California coast?
-
Starlink covers the Southern California coast, Catalina and far offshore, but speed and stability depend on your Starlink plan (use on the open ocean needs a plan that allows it), a clear view of the sky and how busy the network is. We mount the dish where it sees the most sky and can add 5G backup through a Peplink router.

#376 Common question asks
Can you come to my slip to install Starlink in Marina del Rey or Long Beach?
-
Yes. We install Starlink at your slip or private dock anywhere from Marina del Rey to Newport Beach, or at our San Pedro shop. A trip fee by distance applies to each visit, from $30 in San Pedro to $110 in Newport Beach, with no trip fee at the shop.

#374 Common question asks
Do you install Starlink Maritime systems on yachts and fishing vessels?
-
Yes. We install Starlink Flat High Performance antennas on yachts, sailboats, trawlers and fishing boats, along with the power supply, router and onboard Wi-Fi. Use on the open ocean needs a Starlink plan that allows it.
