With a total of 6 patents to his name, Aihara's innovations have enhanced the performance and reliability of marine engines.

Latest Patents

One of Aihara's latest patents is for an outboard motor that incorporates a centrifugal clutch system between the engine crankshaft and the drive shaft. This design features an exhaust pipe with an outlet submerged under water during operation. The exhaust pipe is equipped with an exhaust vent positioned above water, allowing atmospheric air to flow into the exhaust pipe during reverse rotation. This prevents the internal combustion engine from functioning as a suction pump, which could introduce water into the engine cylinder. Another significant patent is for a variable propeller for boats. This propeller includes variable-diameter main blades and stationary subsidiary blades mounted on a propeller boss. This design enhances low-speed driving properties and high-speed performance. When the main blades are closed, the propeller diameter is minimized, and when opened, the blades align to maximize efficiency.
