We want you to be happy with our products. If you purchase a SURFMODE system and simply cannot get it to work on your boat, send it back within 30 days of purchase for a refund. SurfMode Viper cannot be returned. We simply cannot guarantee that you'll be able to learn how to surf a PWC in 30 days. Also, if you are buying a Maverick for a Jet Boat - we require you speak with one of us, before you buy - we want to set expectations.
