A first sheet spring member 80 is provided in a rear part of a bottom surface of the battery receiving recess to urge the battery upward. A latch member 66 provided in a rear end part of the battery receiving recess engages a rear end of the battery against the spring force of the first sheet spring member.

Abstract: An outboard motor configured so that an engine is covered by an engine cover, an intake opening is provided to both sides of the engine cover, and air drawn into the engine cover from the intake opening is introduced to a throttle body. A discharging/interference-type muffler is provided partway along an intake channel for guiding air from the intake opening to the throttle body. The discharging/interference-type muffler is provided vertically in the interior of the engine cover, and the interior of the discharging/interference-type muffler is divided in two in the vertical direction.

Abstract: An outboard engine unit capable of efficiently cooling the interior of an engine cover is disclosed. The outboard engine unit includes a cooling opening capable of guiding air to an interior from an upper part of the engine cover, a first intake channel having a first outlet open to an upper front end and communicating with the opening, a partition wall disposed so as to be oriented substantially in a perpendicular direction below the first outlet; and a second intake channel extending substantially in the perpendicular direction along a rear wall of the engine cover rearward of the partition wall. The outboard engine unit is configured so that air directed from the cooling opening to the interior of the engine cover is directed to the throttle unit via the second cooling air intake channel.

Abstract: An intake system for an internal combustion engine has an intake silencer 30 provided with an expansion chamber 33, and a connecting pipe 40 having an inlet 46 through which air from the expansion chamber flows, and an outlet 47 through which air flows toward combustion chambers. The connecting pipe 40 is made of an elastic material having rubber elasticity, and has a connecting part 41 connected to the intake silencer 30, an inner tubular part 42 extending from the connecting part 41 into the expansion chamber 33 and having the inlet 46, and an outer tubular part 43 connecting to a throttle device 50. The wall 42w of the inner tubular part 42 is provided with a communication opening 44 for connecting the expansion chamber 33 and the air passage 45 to make the expansion chamber 33 serve also as a resonance chamber. The outer tubular part 43 of the connecting pipe 40 is shorter than the inner tubular part 42 of the same.
