Model Features
YC6L boat engine adopts advanced BOSCH electronically controlled high-pressure common rail system, which meets IMOTierll emission requirements. Ideal power source for boats.
Fuel System
> Electronically controlled high pressure common rail system, good atomization, sufficient combustion, fast transient speed regulation and small fluctuation, safe and reliable.
Oil system
> The machine is equipped with auxiliary components such as filter, filter, oil cooler, etc. to ensure the reliable operation of the system.
Cooling water system
> The main shell of the seawater and fresh water heat exchanger adopts cast aluminum structure, and the parts in contact with the water at both ends are sprayed with plastic, which has strong anti-corrosion ability, and the wet exhaust pipe can effectively reduce the exhaust temperature.
Intake and exhaust system
> Turbocharger technology, sufficient intake air, water-to-air cooler technology, increase intake air density, sufficient combustion, and environmentally friendly emissions.
Electrical System
> Electric starter motor, ECU, vehicle wiring harness, on-machine instruments, remote instruments, speed, oil pressure, water temperature, boost pressure and other related sensors, with good monitoring performance.
Gas red body, cylinder head
> Alloy cast iron with high degree of strengthening.
Crankshaft, Piston, Connecting Rod
> Integral crankshaft, sliding bearing, small size, light weight, compact structure and high reliability.
> Aluminum alloy piston; adopts internal cooling oil channel structure, cooling spray hook for oil spray cooling, effectively reduces temperature and improves reliability; connecting rod is made of alloy steel material, high explosion pressure design, high safety factor, to ensure the reliability of key moving parts .

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.
