Follow the winterization procedure in the operator's guide that you received with the motor. Anti-freeze is not needed in an outboard motor. Make sure that the engine is left if the vertical postion for long enough to fully drain out any water after the winterizing. It is also recommeded to store it vertical if possible.
You may change the gear oil if you wish or if it is due but at least check it for any water or water mixed with the oil before storage.
There are articles and videos on storage procedures that can be found online.

The factory recommends that a properly trained technician service your Johnson or Evinrude outboard motor. Should you elect to perform repairs yourself, use caution, common sense, and observe safety procedures in the vicinity of flammable liquids, around moving parts, near high-temperature components, and working with electrical or ignition systems.
The information offered here is only general in nature and should not be construed as complete factory approved procedures, techniques, or specifications. Always use the proper service manual for your motor, up-to-date service literature, the correct tools, and have an understanding of how to proceed with troubleshooting and repair methods. If you are unsure or uncomfortable with a procedure, a situation, or a technique, enlist the services of a factory trained technician.
