Driveshaft with a resiliently deformable cushioning structure secured thereon

摘要

A watercraft includes an engine having an output shaft. A coupling structure is provided on one end of the output shaft. A driveshaft has an engine connecting axial end portion. The engine connecting end portion provides a first cooperating interlocking structure. A resiliently deformable cushioning structure has a second cooperating interlocking structure and is mounted to the engine connecting end portion with the first and second interlocking structures interlocking with one another to secure the cushioning structure on the engine connecting end portion. The coupling structure couples the output shaft and driveshaft together so that powered rotation of the output shaft is transmitted to the driveshaft. The cushioning structure is positioned between the engine connecting end portion and output shaft such that the cushioning structure prevents the engine connecting end portion from abutting directly against the output shaft during relative movement of the driveshaft and output shaft towards one another.
