An outboard motor includes an engine bottom cover member which is disposed in a space between a front portion of an under cover and an upper portion of an outboard motor attachment mechanism and conceals a bottom end portion of an engine from view at least in a lateral direction of the outboard motor. The outboard motor having such concealed engine bottom portion is sightly in appearance. The engine bottom cover member is formed integrally with an under cover and, hence, it can be assembled automatically when the under cover is attached to the under case.

Outboard motor

An extension case in which an oil pan is accommodated includes on its left and right side surfaces mount receiving recesses for receiving a pair of lower mounts, respectively, and further an oil drain recess on the right side surface to which a drain bolt is exposed for draining oil from the oil pan. The oil drain recess is formed upwardly of the right mount receiving recess with a partition wall interposed therebetween and these recesses are opened at the right side surface of the extension case. When the extension case is produced by casting with two die parts which are divided into left and right sides, the arrangement makes it possible to form both the recesses simultaneously with use of one of the die parts.

Outboard engine structure

A drive transmission system for a vessel propelling equipment 1 provided with a clutch operating device that can easily be installed comprises a shift slider 40 axially slidable within a propeller shaft 9 to move a clutch gear 30 through a clutch shifter pin 38 inserted through the propeller shaft; and an operating member capable of operating the shifts slider from above a gear case 5; the operating member includes: a shift fork 50 engaged with 9 fork engaging portion 35c of the shift slider, to move the shift slider; a guide member 59 supporting the shift fork movable in a specific direction; a rotary rod member 55 engaged with a rod engaging section 50b of the shift fork to move the shift fork; and a support member 51 drivably supporting the rod member and fixedly supporting the guide member, thereby sub-assembling the rod member and the guide member to transmit the operation of the rod member to the shift fork; the shift fork is so assembled to be engaged with the fork engaging section of the shift slider by fitting the support member from above in a specific fitting section in the gear case, thereby transmitting the movement of the rod member to the shift slider.
