without residual oil, Method 2 using the fill/vent screws is the only

recommended fill method.

Draining the Gearcase

1. Trim the engine out to approximately 30 degrees.

2. Open the hood. Refer to Hood Opening.

3. Remove the cap from the gearcase fill/evacuation tube and install the fluid

drain hose from the fluid transfer pump assembly onto the tube. The lock

button on the fluid drain hose will snap into place.
