Model Features

The YC6K boat engine adopts electronically controlled high-pressure common rail technology, which meets IMO Tier II emissions, has good power and economy, and is an ideal matching power for the main engine of official ships, yachts and tourist ships.

YC6K


Fuel System

>Two-stage diesel filtration, strong adaptability to oil, good safety and reliability.

Cooling system

>High-efficiency oil cooler, water-cooled exhaust pipe technology, high-efficiency cooling, effectively reducing the temperature of the engine room, good thermal balance, and more reliable.

Gas distribution system

> Four-valve technology, sufficient intake air and sufficient combustion, using Yuchai's proprietary piston ring sealing technology and valve oil sealing technology, lower lubricating oil consumption.

Gas red body

>High-strength cylinder block structure, integral crankcase structure, high safety factor, good reliability, open side windows in the body, one cover per cylinder design, easy maintenance.

Crankshaft connecting rod

〉High strength alloy, high explosion pressure design, good dynamic balance,

Low vibration and noise, safe and reliable.




Intake and exhaust system

>Stainless steel air filter element, corrosion-resistant, washable, water-cooled exhaust pipe technology, effectively reduce the temperature of the engine room.

Electrical System

>Double-wire structure generator and starter can effectively avoid the electrochemical corrosion of the hull; equipped with digital intelligent machine side and remote monitoring instruments; dual-energy start-up is optional.

Combustion System

> The overall cylinder head has four valves, and the fuel injector is placed in the middle. The fuel is atomized evenly, the combustion is sufficient, and the exhaust smoke is small.

Oil system

>Internal cooling oil channel piston, one-ring cooling technology, effectively reduce piston temperature and oil consumption.

power transmission system

> Gear train with patented wire meshing technology; strengthened crankshaft front and rear structure, lower noise and stronger front output capability

TSD Diesel Inboard vs Gasoline Outboard

Diesel has a high flash point, is not easy to burn, and is safer.


Fuel types more compliant with government requirements and easier to buy.


Higher fuel efficiency and economy, durability.


The initial purchase cost is high, but the maintenance cycle is long and the user operating cost is low.


Greener and emits less CO2 than gasoline


Gasoline has a lower flash point and has a higher chance of an accidental explosion.


More and more government directives require that government ships in the fields of defense, navy, etc., transition from gasoline engines to diesel engines.


Fuel consumption of the same horsepower is about 40% higher than that of diesel outboards.


Low initial acquisition cost and high long-term operating cost.


More carbon dioxide and pollutants.
