Sever 750K





The “Sever 750K” is built for comfort and functionality at the highest levels!  The airboat easily transports up to 2 tons of cargo or 8-10 people.  The all-welded aluminum cabin in installed on this model. 

For ones who loves to fish in the winter and in the off-season this model is especially relevant – it is warm inside even at -30°C. The cabin is glued with double soundproofing and trimmed with carpet, but at the customer’s request it can be trimmed with wood, leather, etc.  On the perimeter of the cabin there are tinted sliding windows, and a transparent sunroof. The cabin on this model makes it very warm and comfortable even at -30 ° C weather, since it has two “Zenit” heaters that are permanently installed under the center console at the feet of the driver and the front passenger and a “Webasto” auxiliary heater in the passenger compartment. The entrance to the cabin is in the middle. A spacious passage allows you to bring in bulk things. The front seats for the driver and passenger are separate from each other and are light and comfortable. In the passenger compartment there are three soft solid seats, which can accommodate 8-9 people. The largest seat is permanently mounted on the fuel tank and to the left and right of it are 2 more soft seats, which have spacious lockers underneath them, solving the issue of transporting small personal belongings. all the soft seats of the second passenger row will create a full sleeper for 3-4 people. Over the seat under the ceiling along the entire length of the cabin on both sides are comfortable shelves. Inside the cabin is illuminated by hour yacht LED lights, working independently of each other. 

The front deck is a two-level deck: the lower open platform with two closed spacious and very functional lockers on the left and right, the upper one is located above the luggage compartments and has guard rails. A winch is installed on the nose. The decks of the cabin and the bow compartment have a non-slip cover, which makes the boat’s movement safe and reliable.

The models of our airboats have a wide range of applications: they are purchased for personal use and for public needs, like fishermen and hunters, as well as nature conservation organizations, both nature lovers and search and rescue services, both for summer and off-season and winter.


The design of the boat is a combination of an all-welded aluminum hull, which is a reliable foundation of the ship, 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 or ice hummocks. 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, 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 airboat.

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.

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. Two vertical keel (steering) controls are located behind the screw. Batteries are installed in front of the fence in special plastic boxes.


The “North 750K” 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.
