Reliable Repairs, Rebuilds & Maintenance
Marine engines work hard, often in harsh conditions, and they deserve a service team that understands the load they carry. Our servicing covers everything from basic maintenance to advanced repairs, including injector overhauls, heat exchanger cleaning, oil and fuel testing, and complete engine rebuilds. We use industry-proven tools and techniques to deliver precision results that help you avoid downtime and extend engine life. We also offer laser alignment and pressure testing to make sure every component is working in harmony.

If you’re noticing sluggish performance, unusual noise, overheating or fuel inefficiency, don’t wait. Our qualified marine technicians can quickly identify the issue and get you back on the water with confidence.
How often should my marine engine be serviced?
A marine diesel engine should generally be serviced every 100–200 hours of operation or at least once a year, whichever comes first. Regular maintenance includes changing the oil and filters, checking and replacing belts, cleaning air and fuel filters, inspecting the cooling system, and testing the battery. If your vessel sees heavy use or runs in demanding conditions, more frequent checks are recommended. Staying on top of servicing helps prevent breakdowns and extends the life of your engine.
What are signs my marine engine needs servicing?
Common signs include difficulty starting, decreased performance, unusual noises, increased exhaust smoke, or overheating. You might also notice increased fuel consumption or irregular engine idling. These symptoms can indicate issues like clogged filters, worn injectors, overheating due to blocked coolers, or internal wear. It’s important to address these early—minor problems can escalate quickly in marine environments. Scheduling an inspection at the first sign of trouble can save time, money, and major repairs.
What does a full marine engine service include?
A full service typically involves oil and filter changes, fuel system inspection, air filter replacement, coolant system flush and pressure test, belt and hose checks, injector inspection, and overall engine diagnostics. Advanced services may include ultrasonic bath cleaning for heat exchangers, laser alignment of components, and compression testing. The goal is to ensure every system is clean, lubricated, calibrated, and running efficiently.
