发明名称 Marine propulsion device
摘要 A device for adapting a brush cutter or whipper snipper to perform as a marine propulsion unit is disclosed. The brush cutter or whipper snipper must have an engine driving a first shaft (2) rotatably mounted within an outer shaft. The device includes a two or three bladed propeller with low pitched blades (5) connected to a second shaft (4), and a propeller housing that supports the second shaft. A set of brass drive inserts (6-8) of particular shapes are used to connect the first and second shafts to allow the propeller to be driven by the engine. The propeller can be used for propulsion of a small watercraft.
