Sever Phantom 850K






The peculiarity of the Phantom 850K is the larger size of the cargo platform, it is the first airboat with the inflatable corpus with the load capacity of up to 3 tons. So, for example, the boat is able to take to aboard the passenger car “Niva,” and glide with it on the water at a speed of up to 48 km/h. 

Another important difference is the location of the doors. Two doors are installed like a car: right and left of the driver and passenger seats. The cabin is double noise insulated to provide sound comfort and accommodates up to 5 people.

The new cargo version of the model of the Phantom 850K Airboat was requested by our customers, the essence of which was the creation of a powerful, extra-lifting, convenient and comfortable water equipment. This model differs from the “Phantom 750K” with the size of the front cargo platform – it is increased to 3.8 m in length and 2.27 m in width, and a reduced cabin, which can accommodate 5 people comfortably.

This impressive cargo version of the Sever airboat is perfect for both commercial organizations and government agencies who need serious water technology for long-distance cargo transportation, and a warm cabin with several heating options will allow the Phantom 850K to be operated in various climatic conditions at any time of the year.

Phantom 850KA : (bus-type) – already today is the created version of the largest for nowadays airboat of the production company “Sever” for passenger transportation in the extreme sever with the salon for 12-14 people. 


The design of the boat is a combination of an all-welded aluminum hull, and an inflatable body located at the base. This acts as a shock absorber for softening impacts when moving on obstacles protruding from the water. It is the inflatable body that takes over all the destructive bottom impact loads, absorbs the impact and, after passing through the obstacle, restores its original shape.

The inflatable boat hull is made of high-strength synthetic fabric with a double-sided polymer coating of PVC with the addition of thermoplastic polyurethane. Applied fabric is environmentally safe, wear-resistant, has high climatic and strength characteristics.

The bottom of the boat is protected by polymer scales, which adequately withstand both temperature changes and mechanical impacts. Scales are polymeric plates, each of which is attached with a cord to the bottom of the boat overlapping each other, in general forming a multi-stage protection of inflatable cylinders. When moving along boulders protruding from the water or ice mounds, each plate is elastically deformed and bends, damping and evenly distributing the load throughout the bottom of the boat. Each scales, in addition to the protective function, performs the role of a transverse version and ensures high speed performance for the aerodrome.

A bulwark with a loose bar along the entire perimeter is a side protection of the boat. The water on board flows into the scuppers – special barred holes in the aluminum casing. Cylinder pumping valves are located in easily accessible places throughout the boat’s hull.

The rigid welded cabin is an aluminum structure with two frontal, four side and two rear windows, with two swing doors to the right and to the left. All “Triplex” glasses are tinted with thermal film. The side windows are sliding.

Interior trim as standard – carpet, but any options are possible: leather, wood, etc.

The front loading area has a high reinforced double-row guard rail, with the possibility of fastening the cargo line for it. An electric winch can be installed on the nose.  The deck in the cabin has a non-slip polymer coating. The cargo platform is covered with a moisture-resistant non-slip plywood.

The standard equipment of the boat includes: two soft chairs to the left and right of the doors of the cabin, a solid soft seat behind the seats, an all-welded fuel tank with a capacity of 400 liters under the solid seat, a glove compartment in front of the passenger seat, a dashboard with a steering column, “Zenit” heaters, Eberspacher Airtronic, two batteries, interior lighting with yacht LED lights, rear-view mirrors.

In an additional configuration, the installation of an electric winch, a lighting headlamp, a transparent sunroof on the roof is provided.

In the rear part of the airboat there is a propeller-driven unit, which is a single assembly unit consisting of an aluminum all-welded fence for the screw and a longitudinal-transverse motor tar, on which an engine is fixed using shock-absorbing silent blocks. The engine is equipped with a reduction gearbox, on the flange of which the air screw is fixed. Four vertical keel (steering) controls are located behind the screw. Batteries are installed in front of the fence in special plastic boxes.


“Phantom 850K” airboat has a Chevrolet LS-3 Engine .
Power : 430 hp
Volume: 6200 cm3
Maximum Speed: Up to 100/150 km/h
Fuel Consumption: 35-90 l/h


Drive from the engine to the propeller is carried out through the lowering, single-stage, cylindrical, helical gear reducer. The gear housing is made of high-strength aluminum alloys. The gears undergo chemical-thermal treatment and rolling, have high wear resistance and strength. The connection to the motor shaft is via an elastic coupling that is integral with the flywheel.
