MG-31F engine with 330 hp with a pulling propeller over the boat on racks; metal structure with linen covering of the wing and empennage, distinguished by high general and local strength, tested during flights and landings (more than 120% of the design loads). The entrance to the cockpit is through doors in the sides of the boat, dropped in an accident, the entrance to the four-seater passenger cabin is through a round hatch in the deck behind the wing, which also served for the shooting installation.

Control cable, double, cross-over steering wheel in flight. Chassis - with a breaking rack, cleaning and release is manual with a chain transmission. On the semi-axle of the chassis, skis from the I-15 bis aircraft could be installed instead of the wheels, which rose when landing on the water. Oil-air depreciation. It was planned to lift the plane on a hook.

The aircraft began to be designed at the end of 1938, released in the spring of 1940, first flew on June 16, 1940 (pilot E.O. Fedorenko). By September 1940, its factory and state tests were completed and it was decided to build a series of Sh-7 aircraft.
