High rpm, high performance throw-away diesels have their place in planing pleasure craft that rarely get too far from the local yacht club. But why put one of these engines, even a derated version, in your commercial boat or long range cruising yacht? These vessels need a real, heavy duty diesel that produces high, prop twisting torque at a rational rpm. They need a conservatively rated engine with long life features like the L1276A2.
Initially designed for Alaskan fishermen, Luggers have always been dependable. Used as prime movers on Northern Lights marine generator sets, they are well known by commercial and pleasure craft owners for long life and smooth, quiet operation. Today, electronic fuel injected engines like this L1276A2 are adding US EPA Tier II compliance to Lugger's reputation for reliability, simplicity and durability.

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 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.

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.
- Reliable
- Efficient
- Economic maintenance
- Environmental-friendly

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
