Marine Generator Service & Repair in Florida

Marine Generator Service for Yachts Worldwide

Marine generator specialists install, service, and repair the gensets that supply a yacht’s electrical power at anchor and underway. Their work covers diesel generator engines, alternator ends, sound shields, cooling and exhaust systems, and the controls and transfer switching that bring power online. Common problems include hard starting, overheating from raw-water cooling faults, low or unstable output voltage and frequency, excessive smoke, vibration, and impeller and exhaust-elbow failures. Because a genset combines an engine and an electrical generator, good techs diagnose across both domains, checking fuel, cooling, and load on the engine side and windings, regulation, and connections on the electrical side. Regular service prevents the most common failure: cooling-related shutdowns from neglected impellers and strainers.

When hiring, look for factory training on your brand (Onan, Kohler, Northern Lights, Fischer Panda), marine diesel expertise, load-bank testing capability, and strong references for both engine and electrical diagnosis.

Frequently Asked Questions

Q: Why does my generator keep overheating or shutting down?
A: Most often a raw-water cooling fault: a worn impeller, blocked strainer, scaled heat exchanger, or failing pump. A tech checks raw-water flow and the cooling circuit first.

Q: How often should a marine genset be serviced?
A: Service by running hours per the manufacturer, commonly every 250 hours or annually, including oil, filters, impeller, and a cooling-system check.

Q: My genset runs but voltage is unstable. What’s wrong?
A: Could be the voltage regulator, worn slip rings or brushes, winding issues, or unstable engine speed. Both the engine governor and alternator end need checking.
