Marine Services We Offer

Maintenance / Repair

Regular maintenance is essential for safe vessel operation.
At Mizuno Marine, we carefully inspect the condition of engines and related auxiliary equipment, and carry out parts replacement and servicing as needed.
Although the appropriate interval depends on the operating environment and frequency of use, we generally recommend periodic inspections and maintenance every six months to one year.
By helping prevent problems before they occur and maintaining a comfortable cruising environment over the long term, we protect the safety and value of your vessel through reliable maintenance.

Engine Overhaul

Engine overhauls are an important form of maintenance, not only when a failure occurs, but also as a preventive measure against performance deterioration and trouble caused by long-term use.
At Mizuno Marine, we first diagnose the condition of the engine, then carry out thorough disassembly, cleaning, and parts replacement as required. In addition, by conducting bench testing (onshore load testing), we help minimize post-installation issues and reduce the need for adjustment work after the engine is installed on the vessel.
With proven technical expertise and a well-established parts inventory system, we provide fast and reliable turnaround.
