For motorboat use, Yanmar makes main engines up to around 300kW. Like sailboat propulsion units, their reliability is legendary; but they are also light, compact and powerful.
The Saildrive has been found to improve boat balance, give more maneuvrability and better thrust. Drive by the famous Yanmar diesels, these Saildrives put a lot of dependable power in the right place in a boat.
Combustion power acts directly on the toroidal piston crown, boosting energy, decreasing thermal losses. Extra high output creates the tough torque needed for heavy duty jobs.
Now instead of fickle performance common to so many gasoline engines, the diesel outboard presents operational savings and long-term strengths that make pure sense to the commercial operator.
If you are looking for a silent, compact, power source, with minimum fluctuations, the new YDG is waiting for you.
These generators are purpose built to match the engine to the constant running load of the submersible pump, and alternator to the high starting capacity of the pump motor.

High performance straight six
For boats, the ability to slot an engine as low down as possible, or to mount twin engines low in the vee of the boat has been critical. The straight six has thus become the configuration of choice, as the crankshaft is still not as long as to require heavy strengthening, there is more capacity advantage over a four, and a six is far narrower than a vee-eight.

Mounting
The mountability is excellent due to its flat top, and due to its narrow profile. Repowering a gasoline engine boat is now a pleasure, for this engine has more muscle and endurance to match virtually whatever was previously being used.

Features

  • Race proven performance is inherited. Power-to-weight ratio is even more startling. Endurance and fuel economy are at a level that only a diesel could achieve.
  • It follows current user trends, ie the demand for more power and more speed. And because it is a diesel, smaller fuel tanks can be used saving hundreds of kgs of weight in a fast boat. A speed increase becomes immediately possible.
  • Direct injection using ultra-high-pressure fine mist injectors makes for excellent economy together with superb performance, yet there is minimal smoke under hard use conditions. Fuel savings, precious energy savings, and an increase in safety accompany the change to a diesel.
  • All service points are conveniently placed high on the engine. Renowned Yanmar reliability and parts backup complete the package.
  • An engine that will dramatically lift the performance of virtually ANY hull, and likely put you in the race winners seat, if you so desire.

A powerful new force in motorboating
Featuring Yanmar's latest lightweight engine construction technology in a compact package, this power plant exhibits superb fuel efficiency and a power-to-weight ratio that makes possible a higher top speed and a longer cruising range using the same fuel tank.

The increased horsepower in this straight 6 cylinder engine is obtained from a longer stroke, along with a more aggressive turbo/intercooler and tune settings. It also features 4 valves per cylinder and an extra high pressure fuel injection system.

Dimensions of 905mm (35.63in) high and 824mm (32.44in) wide, and with only 825kg (1815lbs.) of engine weight makes for a power installation that is lightweight indeed.

We expect the smooth power, together with the flat torque characteristics and low fuel consumption figures of the 6CX-GTE2 will make it an outstanding choice for any fast boat. This engine is set to become the "world power plant" for the motor boat enthusiast.

Easy on the maintenance man
An overall, simple-to-service design features cylinder inspection ports in the block. These allow at-a-glance checks of crankshaft and bearings and also ease maintenance work by making head removal unnecessary.

Yanmar Spare Parts Its extraordinarily low fuel consumption is a result of this super-precise FIE and its direct injection system-the first ever to go into this type of engine. Now instead of fickle performance common to so many gasoline engines, the diesel outboard presents operational savings and long-term strengths that make pure sense to the commercial operator. When it comes to marine diesels, reliability is most highly valued factor of all. Each Yanmar diesel has been designed and manufactured using knowledge accumulated steadily by us since our founding in 1912. They are built for heavy loads and long running hours and can be matched up with any of the Yanmar engine protection or control systems. If you are looking for a high quality generator, consider one of the models built by Yanmar. Yanmar was founded in 1912 and developed the world's first commercially viable small diesel engine in 1933. For boats, the ability to slot an engine as low down as possible, or to mount twin engines low in the vee of the boat has been critical. The Saildrive has been found to improve boat balance, give more maneuvrability and better thrust. Drive by the famous Yanmar diesels, these Saildrives put a lot of dependable power in the right place in a boat.
