Abstract: A portable pressurized personal watercraft (PWC) flushing and winterization system that gives consumers a simple and convenient PWC marine engine pressurized flush and winterization option. The PWC flushing system generally includes a compression tank with a manual or electric pressure-regulated pump (ac or dc) connected by coiled hose assembly through a stop valve, through a pressure regulator to the existing water-flush connection on most PWCs. The flushing and winterization system includes a flush chemical concentrate that is introduced into the tank and mixed with the proper amount of fresh water, and the tank/pump/regulator combination maintains a regulated output pressure of chemical or anti-freeze into the PWC engine. In addition to pressure-regulation, the amount of flush solution or anti-freeze is demarcated by level-indicator gradients on the tank, and visual monitoring of the operation of the device is possible through a clear hose assembly.
