Abstract (en)
[origin: JPH01119497A] PURPOSE: To protect an underwater part of a connecting rod link works by simple means by moving a connecting rod to a protecting position immediately after stopping a motor, and moving the connecting rod to a position corresponding to a neutral position of a propeller vane when the motor is started. CONSTITUTION: After immediately after stopping a motor, a connecting rod 20 is moved to a position capable of being protected from the impact of a foreign material, and when the motor is started, the coupling bar 20 is moved to a position corresponding to the neutral position of a propeller vane 2. With this structure, when watercraft is not operated, an adjustable link works part laid underwater can be housed in a boss 4 or a bearing housing 26 for protection without providing a special protecting means. When the motor is started, the adjustable linkage structure part is positioned at the neutral position. With this structure, adhesion of the foreign grains in the adjustable linkage structure part can be protected by a simple means without providing a special protecting means.
