Arka outboard 7.5 kW

ARKA OUTBOARD 7.5 kW

Solid materials stand for quality. Due to its robust construction, this ‘vandal-proof’ outboard motor is ideal for private use but also for the rental entrepreneur.

The motors are available as short and long shaft and optionally equipped with a remote control with throttle, ignition switch and battery monitor. For steering, the engine is then equipped with a rudder instead of a throttle handle.

Seal

The submersible motor is equipped with a special mechanical shaft seal. This shaft seal has high wear resistance and pressure resistance. To protect it from external influences, it is preceded by a labyrinth and an oil/dirt barrier.

Material

Arka outboards are made of seawater-resistant aluminium and stainless steel. By placing the right anode for your sailing area on the engine, a high level of corrosion protection is obtained, which extends the lifespan of both the engine and the ship.

Efficiency

Electric propulsion is one of the most efficient forms of propulsion for a ship. The efficiency is obtained by a correct combination of engine, speed, and propeller. It all sounds very logical, but to achieve this efficiency, a lot of testing is required. We have succeeded in developing electric outboard motors that, in addition to having the highest efficiency, are also among the quietest. Arka outdoor drill motors are built according to the direct drive principle, which means that the driven shaft is the same as the propeller shaft. As a result, there are no noise-producing components present in the engine. By applying an industrial-grade motor controller, the conversion losses are minimal.

Plug & play

The structure of an Arka outboard motor is modular. In addition to the use of dimensions, which is common in shipbuilding, the connections have also been standardized. After purchase, all you must do is install the engine on your ship, install the batteries and connect them. Commissioning the motor is then simply connecting the plugs.

Sustainability

Arka outboards cannot pollute the water and have no carbon and nitrogen oxide emissions. They are among the cleanest engines in the world. The lubricants that are used come from the food industry and therefore meet the highest possible requirements. It is for this reason that many drinking water reservoirs are only sailed with Arka drives.

Power

Once you have assessed the weight of your vessel, the choice of propulsion is as follows:

Install at least 1.2 kW per 1000 kg. Ship’s weight to be able to sail at a speed of 70 percent of the hull speed. Installing more than 3.5 kW per 1000 kilos (this is sufficient to sail at hull speed) is not necessary.
