The injection pump is the most precise component in your diesel engine. It meters the diesel, pressurises it to very high pressure and distributes it to each injector with microsecond timing. Because it leaves no room for improvisation, DAM Marine offers a complete range of genuine Yanmar and high-quality replacement injection pumps and components to keep your boat reliable.
In simple terms, it manages three vital functions at the same time. That is what makes it essential, but also very sensitive to fuel quality:
Note from our mechanics: the internal elements of the pump are adjusted to micron tolerances and lubricated by the diesel itself. Water and impurities are its worst enemies. Water causes immediate seizure, while microparticles scratch the internal sleeves.

Not necessarily, provided that you act quickly. Drain the water from the fuel-water separator, empty the filter and prime the system again with clean diesel before attempting to start the engine. If the engine has already run under load for several minutes with water in the system, the internal components may have seized and should be inspected.
Preventive maintenance is essential: regularly drain the bottom of the fuel-water separator, follow the recommended filter replacement intervals and avoid running the boat with the fuel tank nearly empty. A useful winter-storage tip is to keep the tank full to reduce condensation and limit water contamination.
In marine mechanics, guesswork has no place. Your pump reference is strictly linked to your engine generation. Two pumps that look identical can have completely different internal settings.
To find the right part, have the following ready:
Not sure? Our technical team can cross-check your references and make sure you get the right part.
Before blaming your injection pump, always check the low-pressure circuit: clogged filter, air leak, water in the separator or tired lift pump. These lower-cost faults often imitate the symptoms of a failing pump.
If the low-pressure circuit is ruled out, here are the signs of a tired pump:
An injection pump cannot be repaired casually on a workbench. Its calibration requires a professional test bench.
If you carry out the replacement yourself, follow these professional rules:
