Marine Electrical Systems in Mackay: Diagnostics, Repairs and Upgrades

Exposed to moisture, salt, and constant vibration, onboard marine electrics require specialized maintenance to prevent unexpected power loss and component failure on the water. Hiring a licensed marine electrician ensures your vessel’s wiring, charging networks, and navigation systems operate safely under demanding marine conditions.

Based at Mackay Marina, Smooth Torque Marine provides marine electrical diagnostics and installations to vessel owners across Mackay, Airlie Beach and the Whitsundays. We also plan onboard power systems around batteries, charging, monitoring and distribution.

Key takeaways

• Diagnostics and installations: We work across a wide range of marine electrical systems and electronics.
• Onboard power: Our services include battery planning, lithium battery installations, charging integration, monitoring and power distribution.
• Queensland licensing: Our marine electrical service lists licence number 1512977.
• Local support: Our workshop is at Mackay Marina, and we support vessel owners across Mackay, Airlie Beach and the Whitsundays.

Marine electrical services and diagnostics in Mackay

Our team investigates faults in marine electrical systems and electronics, then installs solutions suited to the vessel and its operating conditions. Marine environments expose equipment to moisture, salt and vibration, so electrical systems need to be planned for life aboard a boat.

If you need help with a fault, tell us what changed and which equipment is affected. For a planned installation or power project, explain what you want the system to do and what is already aboard. Our marine electrical service covers diagnostics and installations across a wide range of marine systems and electronics.

Diagnostics vs. upgrades: choosing a marine electrics solution

Diagnostics help identify the source of an electrical issue. An installation adds or replaces equipment. A power system upgrade can involve planning how batteries, charging sources, monitoring and power distribution work together aboard your vessel.

For example, a charging fault may call for fault diagnosis, while a change to the vessel’s power capacity may need a broader system plan. We consider the existing equipment and how you use the boat when planning that work.

We diagnose systems, install equipment and plan vessel power projects. For a repair or refit, tell us about the vessel, equipment and outcome you need so our team can advise on the appropriate next step.

Marine electrical licensing in Queensland (licence 1512977)

We provide marine electrical work under licence number 1512977. Queensland requirements vary by the type of electrical work. Maritime Safety Queensland states that boat owners must engage an electrical contractor for 230 V or 240 V mains work on boats. Maintenance and repairs to low-voltage electrical installations on boats must be carried out by a licensed electrician.

Electrical work	Queensland requirement
230 V or 240 V mains work on a boat	Engage an electrical contractor
Maintenance and repairs to low-voltage electrical installations on boats	Work must be performed by a licensed electrician

Read Maritime Safety Queensland’s guidance on boat electrical standards and licences for more detail on the rules and standards that apply.

Onboard power management and lithium battery installations

We work across a wide range of marine electrical systems and electronics. Our power services include battery and energy storage planning, lithium battery installations, charging integration, system monitoring and power distribution. Depending on the vessel, charging sources may include shore power, alternators, generators and solar.

Capability	Published system scope
Battery and energy storage	Capacity planning, lithium battery installations, monitoring and protection
Charging integration	Compatible shore power, alternators, generators and solar
Vessel power management	Monitoring, onboard loads and power distribution

See our battery and energy storage service and vessel power management service for details. For a system enquiry, tell us the equipment make and model if known, what the system needs to do and what equipment is already aboard.

For projects involving propulsion, batteries and integrated onboard systems, see our overview of marine engineering services in Mackay.

How to prepare an electrical service enquiry

To help us understand the vessel and the electrical issue, include the details you have:

• vessel make, model and current location;
• the system or equipment involved, including its make and model if known;
• what has changed, when it happens and any displayed warning; and
• recent electrical work or the outcome you want from a planned installation or upgrade.

If the fault is intermittent, note when it occurs and which other systems are in use at the time. Manuals, wiring diagrams or earlier service records can also help explain the setup. When you’re ready to get the issue assessed, our boat mechanic booking guide explains what details to send with your enquiry.
