An outboard motor having an internal combustion engine that causes rotation of a driveshaft, a planetary transmission that operatively connects the driveshaft to a transmission output shaft, a band brake configured to shift the planetary transmission amongst a forward gear, neutral gear and reverse gear, a hydraulic actuator is configured to actuate the band brake, and a cooling water circuit that extends adjacent to the hydraulic actuator so that the hydraulic actuator exchanges heat with cooling water in the cooling water circuit.

Outboard motor and lubricating oil introducing method thereof

An outboard motor includes: a driveshaft housing configured to accommodate a driveshaft; and a gear case bulging laterally below the driveshaft housing and configured to accommodate a gear device, wherein an inside of the driveshaft housing communicates with an inside of the gear case, an introduction port for introducing lubricating oil into the gear case is opened on the driveshaft housing, and a confirmation port for causing the lubricating oil introduced into the gear case to flow out is opened on a front end side of the gear case.

Cowlings and latching assemblies for cowlings on marine drives

A latching assembly is for a cowl on a marine drive, the cowl having a first cowl portion and a second cowl portion that mates with the first cowl portion. A latching device is configured to latch and unlatch the first cowl portion to the second cowl portion. An actuator actuates the latching device. A flexible connector has a first end coupled to the latching device and a second end coupled to the actuator. Actuation of the actuator pulls the flexible connector to rotate a pulley and actuate the latching device. One of the first and second ends has a spherical bearing that is nested in a cylindrical bearing and seated in a cavity in the pulley. Pulling on the flexible connector pulls the spherical bearing against the cylindrical bearing such that the cylindrical bearing is pulled against the cavity in the pulley, thereby causing the pulley to rotate.
