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.

A gearcase assembly for a marine drive has a torpedo housing having a cavity for containing lubricant, a passage configured for filling and draining of the lubricant to and from the cavity, a first bore and a second bore which connect the passage to opposite sides of the cavity, respectively, and a combination filling/draining device having a filling configuration in which inflow of the lubricant to the cavity via the first bore is restricted, a draining configuration in which outflow of the lubricant from the cavity via the first bore is comparatively less restricted, and a closed configuration in which outflow of the lubricant from the cavity via the passage is prevented.

A motor fluid draining tool kit assembly for collecting oil expelled from an outboard motor includes a flexible bag suspended from a hanger rod that is affixed to an L-shaped mounting bracket and two elastic straps. The assembly can be removably attached to an outboard motor beneath a valve by tying the two elastic straps around the assembly and the outboard motor. Fluid can then drain out of the motor and into the flexible bag. After the fluid is drained, the flexible bag can be removed from the hanger rod for disposal of the fluid.
