Darwin Generator Servicing
There’s nothing more frustrating than losing power when you're out on the water—especially if your generator is the lifeline keeping systems running. At ElectroMech Marine in Darwin, we specialise in marine generator servicing that helps prevent breakdowns and keeps your power supply stable when you need it most. Salt, moisture, vibration, and long operating hours all take a toll on marine generators. That’s why we focus on preventative care, thorough inspections, and detailed repairs to ensure long-term performance and safety for your onboard systems.
We service a wide range of brands, including Cummins Onan and Victron Energy systems, and tailor our work to suit your vessel’s power setup. To book a service or generator health check, submit an enquiry form or email us today and let us help you stay powered and prepared.

Reliable Repairs & Preventative Care
A reliable generator means peace of mind—especially on extended voyages or when running essential equipment on commercial vessels. Our generator services include routine inspections, oil and filter changes, spark plug and air filter replacements, leak detection, coolant checks, load testing and more. We also carry out fault diagnostics and complete rebuilds when needed. Whether you’re dealing with start-up issues, voltage fluctuations, or reduced performance, we can quickly identify the root cause and provide expert repairs.

We work with portable, fixed, and integrated marine generators, ensuring proper operation and load balance for whatever your setup requires. Regular servicing helps extend the life of your generator and prevents major failures that could leave you stranded or out of operation.
How often should my generator be serviced by ElectroMech Marine?
Generators should be cleaned and checked for leaks at least once a year, with oil changed every 60 hours. This includes replacing oil filters. Air filters and spark plugs will also need to be checked and replaced and you should regularly check your battery for corrosion.
What causes a generator to fail on a boat?
Generator failure can be caused by low oil levels, fuel contamination, battery issues, overheating, poor ventilation, and lack of routine maintenance. Dirty or worn filters, clogged injectors, and corroded terminals can also impact performance. Saltwater exposure increases corrosion risk, which can damage electrical components. Catching these issues early through regular servicing greatly reduces the chance of total failure and extends the generator’s lifespan.
Can I run a generator continuously on a boat?
Yes, most marine generators are designed to run continuously for extended periods, provided they are well-maintained and not overloaded. However, regular monitoring is essential—check oil levels, coolant temperature, and exhaust output during long operation. Overloading or poor ventilation can lead to overheating or damage. If you plan to use your generator continuously, be sure it’s properly sized for your vessel’s electrical demand and serviced regularly.
