From complete engine overhauls to precision injection work, cooling system repairs, and drivetrain rebuilds — Endurance Marine handles it all with the experience and tools your vessel deserves.
When your engine has reached the end of its service life, a proper overhaul is the most cost-effective path to a reliable, long-lasting powerplant. We perform complete marine diesel engine overhauls to manufacturer specifications using only OEM or equivalent quality parts.
Our process begins with a full disassembly and inspection to document every component’s condition, followed by a detailed written estimate before any parts are ordered.
The fuel injection system is the heart of your diesel engine’s performance and efficiency. Worn injection pumps or fouled injectors cause hard starting, black smoke, poor fuel economy, and engine damage.
We use precision test equipment to verify injection pressure, timing, and spray pattern across all major marine engine brands — both mechanical and electronic systems.
Overheating is one of the most damaging things that can happen to a marine diesel engine. We thoroughly inspect, service, and repair both freshwater and seawater cooling circuits to keep your engine at optimal temperature.
Slipping gears, noisy operation, or difficulty engaging ahead or astern are signs your drivetrain needs professional attention. We diagnose and rebuild marine transmissions and outdrives for a wide range of vessels.
A clean, well-presented engine room signals to any surveyor or buyer that the vessel has been properly maintained. Our engine detailing service is the perfect complement to any major service or overhaul.
