Best in Class Life Cycle Cost
Engine Design - Reliable base engine uses common components from the proven K19, K38 and K50 engines. A new cast-iron, ductile single-piece piston with nitride-coated rings and hardened cylinder liner increases durability and reduces maintenance
Fuel System - Modular Common-Rail Fuel System features a simplified design which provides constant high injection pressure regardless of engine speed or load conditions. Benefits include significantly reduced noise and vibration for quiet operation, better idle stability and improved low-end torque
Cooling System - Single-loop cooling eliminates the need for two keel coolers for reduced installation expense. Engine-mounted titanium plate heat exchanger provides superior durability with minimal maintenance requirements
Exhaust System - Water-cooled exhaust manifold cools engine surface temperatures. Design is a cast single piece construction that eliminates potential exhaust leakage
Air System - Mounted or remote marine grade air cleaner with replaceable element reduces maintenance cost. Water-cooled turbocharger optimized for vessel operating conditions and safety
In designing the engines, consideration was given to their intensive use and to the desirability of easy and simple maintenance. These engines feature individual cylinder heads and wide inspection doors in the block, which makes access to the inside parts of the engine easy, and shortens the service time during maintenance and repair processes.
This series comprises six and eight cylinder in-line engines as well as twelve and sixteen cylinder 60º V-bank engines.
Engine Design - Heavy duty, in-line, six cylinder configuration designed for maximum durability-Replaceable wei cylinder liners offer longer life and lower rebuild costs. Forged steel, articulated piston for increased power/torque capacity and gallery cooled for maximum durability
Fuel System - Reliable Cummins HPI fuel system offers precise fuel injection for less smoke and responsive performance
Cooling System - Single loop, low temperature aftercooled design eliminates the need for two heel coolers for reduced installation expense. Low profile heat exchanger system engineered for simplicity, utilized o-ring seals and piping that eliminates hose clamps for leak-free operation
Yanmar engines just last and last. Superior technology results in state-of-the-art propulsion systems you can rely on. For example, the qualily of the diesel fuel is optimised by superb tillering, including a centrifugal oil cleaner and large oil filter. The 6/8 cylinder heads separately are light enough to be lifted by one person, yet extremely strong. Day to day checks can be carried out via ergonomic access points (front mounted), like the oil dipstick, oil filler, fuel filter, cooling water filling and oil filling.

The D12-800 engine is more powerful and cleaner than the class-leading predecessors and the successful D12 engine concept now delivers more horsepower than ever before. The Volvo Penta D12 is perfectly designed for twin-engine installation in flybridge boats and sport cruisers ranging from 50 to 70 feet.
Engine Design - Low profse tor ease of installation and service. Replaceable wet cylinder liners offer longer life and lower rebuild cost. Gallery cooled pistons for maximum durability
Fuel System - Dependable Cummins FT fuel system can be operated mechanically or with CENTRY electronics for precise engine fueling. Step Timing Control (STC) allows for smooth engine acceleration under load
Cooling System - Keel cooked or engine mounted plate beat exchanger for reduced installation cost and less maintenance. Spin-on Cummins water treatment filters for protection against cooling system corrosion
Exhaust System - Dry exhaust manifold with water shielding for reduced fuel consumption and improved performance
Air System - Marine grade air titers with air Inlet restriction indicator. Twin Holset turbocbargers optimized for marine usage
The 8SY-STP features individual cylinder heads that offer substantial weight savings and are light enough to be lifted and reinserted by one person. Together with a modular design for fewer maintenance operations, electronic diagnostics and easily accessible service points make routine engine care simple and economical.The more power, less weight design allows for maximized torque at low revs, improved fuel economy and reduced emissions.
