Abstract

A seaplane float propulsion system that is configured to provide maneuverability and directional movement of a seaplane subsequent the engine and propeller being deactivated. The present invention includes a first float member and a second float member wherein the first float member includes a first propulsion assembly mounted therein and the second float member includes a second propulsion assembly mounted therein. The first propulsion assembly and second propulsion assembly are identically constructed. The propulsion assemblies are independently controlled so as to provide both directional and rotational movement of the seaplane to which the present invention is operably installed. The propulsion assemblies include elements that are operable to intake and direct water flow in order to create the desired movement of the seaplane in which the seaplane float propulsion system is installed. The propulsion assemblies include an intake element that provides ideal fluid and aero dynamics.
