Outboard motor having seal structure for exhaust release pipe

摘要

An outboard motor includes an elastic seal lid attached to an under cover to form a hermetic seal between the under cover and an exhaust release pipe while closing an opening of the under cover from which an outlet portion of the exhaust release pip projects outwardly. The seal lid includes a tubular seal portion projecting from at leaser one surface of a plate-like body of the seal lid. The tubular seal portion has annular seal lips fitted around an outer circumferential surface of the exhaust release pipe. The tubular seal portion is elastically deformable relative to the lid body to thereby take up or absorb an offset between the exhaust release pipe and the opening of the under cover produced due to cumulative manufacturing and assembling tolerances of relevant parts of the outboard motor.
