Wash the jet-ski using a clean rag and mild detergent to remove any dirt or debris. It is necessary to remove the dirt and debris to prevent the staining or discoloring of your jet-ski while in storage.
Locate any sharp edges or points on the jet-ski. Cover the sharp edges or points by layering extra rags on top of them to prevent them from tearing the cover. Although a quality cover has reinforcment for such areas, layering rags over the sharp edges will help to extend the life of the cover while the jet-ski is in storage. When trailering the jet-ski, you will need to remove the rags as they may not stay in place.
Locate the tag that identifies the front of the cover. Place the front of the cover over the nose of the jet-ski.
Pull the cover over the remaining length of the jet-ski. Make sure the handlebar is fitted into the cover properly. The cover, if it was manufactured specifically for your jet-ski, will have extra material in the correct place to accommodate for the handlebar.
Finish pulling the cover over the rear of jet-ski so that it fits tightly just below the jet-ski's rub-rail. The rub-rail is the rubber rail that wraps around the jet-ski to prevents damage when the jet-ski rubs against a dock.
Locate the front and rear straps on the cover. Fit the straps under the jet-ski and secure the cover by adjusting the straps so that they hold the cover firmly in place.
