Semi-Custom Fit

Semi-custom fit, also known as “styled-to-fit,” means that your cover is manufactured to fit the style, shape, and size of your jet ski. While not as precise as a custom cover, it is highly fitted to your jet ski’s dimensions: length, width, and height. A buckle and strap system included with your cover gives you extra control for a snug fit.


Installing the cover is simple and takes approximately 5 minutes. To start, simply line up the front of the cover on the front of your jet ski. Next, begin unrolling the cover towards the back of the watercraft. When fully unrolled to the back of the watercraft, begin pulling the cover over the left and right sides. Last step is to ensure you have fastened any and all straps to your jet ski to protect from wind gusts.


Due to the size of the cover, most jet ski covers cannot be washed in a washing machine. To clean the cover, you may use a soft tool such as a brush to wipe away debris from the cover. Once excess debris is removed, spray the cover down with a mild soap and water, and allow to soak. After soaking, simply spray the cover down with a hose to wash away dirt and grime. Never use heat to dry your cover. Heat tools will damage your cover and void the warranty.
