Brand familiarity
We work across established marine manufacturers, coordinate factory support where available, and evaluate the complete system before recommending equipment.
Manufacturer names and logos belong to their respective owners. Dealer or service authorization applies only where specifically stated on this page.

Systems matrix
AMS Mechanical follows the fuel, air, cooling, exhaust, electrical, control, mounting, transmission, and load systems that determine whether engines and generators perform reliably.
Diagnostics and service organized around the engine’s operating conditions and supporting systems.
Mechanical and electrical output checked together under realistic vessel load.
Power delivery from the engine to the water, including the interfaces that influence vibration and performance.
The supporting environment that protects machinery, access, inspection quality, and service life.
How the division works
The process follows the complete vessel system—not a single component in isolation. That reduces unnecessary parts replacement and creates a cleaner service record for the next decision.
Hours, load, RPM, temperature, alarms, smoke, sound, fluid use, service history, and recent changes establish when the problem occurs.
Fuel, air, cooling, exhaust, electrical supply, sensors, controls, mounts, transmission interfaces, and generator output are evaluated before parts are selected.
Maintenance, repair, replacement, cleaning, greasing, component coordination, and access planning are completed around the actual diagnosis.
The engine or generator is run under appropriate conditions, checked for stable temperature and output, and recorded for future service planning.
Field evidence
Project images are shown with factual captions so owners, captains, engineers, and yards can understand the type of work behind the service claim.

Open resourceDivision FAQ
The division covers marine diesel engines, gasoline outboards, generators, transmissions, controls, cooling, fuel, exhaust, mounts, belts, hoses, filters, pumps, supporting electrical interfaces, and engine-room reliability work.
Many apparent engine faults originate in fuel delivery, restricted cooling, exhaust backpressure, electrical supply, sensors, controls, mounts, or load. Testing the complete system reduces unnecessary parts replacement.
Use the manufacturer’s hour and calendar schedule and adjust for heat, humidity, loading, storage, fuel condition, and operating pattern. Annual service alone may not be enough for heavily used equipment.
Yes. Engine-room support can include cleaning, greasing, visual inspection, hose/clamp/belt review, filtration, fluid checks, corrosion observations, access review, and documentation as part of a broader maintenance scope.
Yes. Work involving running gear, propellers, shafts, underwater exhaust, through-hulls, mounts, alignment, or restricted access can be coordinated with an appropriate boatyard and specialist vendors.

Planned maintenance
Planned propulsion and generator service should track hours, calendar items, cooling, fuel, electrical output, exhaust, belts, hoses, leaks, mounts, cleanliness, and changes from the last inspection.
