Title: Kouji Koishikawa: Innovator in Outboard Motor Technology
Introduction
Kouji Koishikawa is a prominent inventor known for his contributions to outboard motor technology. He is based in Wako, Japan, and has been instrumental in developing innovative solutions that enhance the performance and efficiency of outboard motors. With a total of 10 patents to his name, Koishikawa has made significant strides in this field.
Latest Patents
One of his latest patents involves an outboard motor and engine design that features a unique body case supported on a swivel shaft through a connecting member. This design allows the swivel shaft to be vertically swingable about a tilting shaft. The engine is mounted at the upper portion of the outboard motor body case, with its crankshaft oriented vertically. A flywheel is positioned at the lower end of the crankshaft, situated between the engine block and the connecting member. Additionally, a dynamo is integrated within the flywheel, and a starter motor is engaged with a ring gear formed around the outer periphery of the flywheel. This innovative arrangement lowers the center of gravity of the outboard motor, making it easier to perform a tilting-up motion with minimal force. Furthermore, the flywheel's placement on the power taking-off side of the crankshaft helps reduce torsional vibration.
