A gearcase assembly for a marine drive has a gearcase having a torpedo housing, a torpedo plug in the torpedo housing, the torpedo plug separating a lubricant cavity containing lubricant for the gearcase and a water cavity containing cooling water for the marine drive, and a shift actuator configured to actuate a shift clutch in the gearcase. The shift actuator retains the torpedo plug in place relative to the torpedo housing.

Gearcase assemblies for marine drives having torpedo plugs

A cooling system for a marine propulsion device provides a water flow directing device, which is generally annular in shape, which has a water inlet extending from it. The water flow directing device is attachable to a gear case of a marine propulsion device and is configured to conduct a flow of water from a water inlet to a passage formed within the marine propulsion device and connected in fluid communication with a water pump that causes the water to flow to a cooling system of an internal combustion engine. The water flow directing device is removably attachable to a seal carrier which, in turn, is attachable to a bearing carrier disposed within an internal cavity of the gear case. A secondary inlet is provided through a surface of the gear case and in fluid communication with an internal annular passage of the water flow directing device to encourage a flow of water into the cooling system when the marine propulsion device is operating at slow speeds or is stationary in a body of water.
