450 hp marine diesel engines for sale


It is difficult to even quantify the importance of a reliable marine diesel engine. Without these expertly and carefully crafted diesel engines, sport fishing boats around the world simply wouldn't have the legs to do what they do. Evolving technology continues to produce efficient and advanced engines for marine applications, whether it's starting a new engine or repowering


For yachts, most boats only get about 100-300 hours of use per year. Heavy duty marine applications average 10,000-15,000 hours of use before overhaul. Regardless of the application, all marine engines have a shorter expected duty cycle than industrial engines, which can typically travel between 500,000 and 1,000,000 miles before overhaul. The reason for the shorter lifespan is that yacht marine engines will run at constant high speed and low rpm for a short period of time. If you think about it, speedboats really only run at high speeds when cruising the fairways and high seas.

Heavy boat applications have a similar usage profile to yachts, except that they run at full speed for longer intervals. In open water, there are no traffic lights or speed limits. Industrial and truck engines mostly run at a slower speed and only increase RPM as the gearbox briefly shifts 5-6 gears. marine engines only run at 1 gear. A common misconception is that marine engines that have been in use for a short period of time are better than those that have been in use for a longer period of time. Idle marine engines are prone to corrosion and lack of lubrication. Truck and industrial diesel engines typically last much longer than their marine brethren due to their constant use. It is this usage profile that drives the engineering differences between industrial and marine engines. The two main reasons why marine engines are built differently to industrial engines are the risk of fire and corrosion. Marine engines are subject to constant moisture and exposure to water. If this exposure to water (usually salt water) is not mitigated, cast iron and steel will deteriorate quickly. Industrial engines usually operate in a dry environment, unaffected by the weather, without having to worry about auxiliary components or fuel leaks on the road.

From a design point of view, there is not much difference between marine and industrial strength diesel engines. It really boils down to the various auxiliary components used for corrosion or fire protection. It is always best to check with a marine mechanic to ensure that an industrial diesel engine is suitable for your application. Running the engine serial number prior to purchase is essential to get an engine that meets your needs.


Our diesel engines are built around a reliable foundation that has earned its merit as a robust and reliable industrial engine. It has been converted to an excellent marine diesel engine based on the latest proprietary technology and techniques.

FAWDE has selected these base engines based on three principles: power, reliability and fuel efficiency. The diesel engine is a well-balanced engine that
