Military-Proven Since 1988

Since 1988, FlushStar has engineered flushing hardware trusted by boaters and marine mechanics who know what salt water does to an unprotected lower unit. What began as a simple direct-connect fitting has grown into the FlushStar flushing system, built to clear salt, sand, and mineral buildup from your outboard's full cooling circuit in one push-button cycle. No ear muffs to align, no guesswork about whether the job got done. Every unit is a 12VDC, Plug n Play system that requires no additional programming, is Made in the U.S.A., and works with nothing more than a garden hose no need to run the engine, and no noise, emissions, or pollution. It works whether the boat is in or out of the water, making flushing hassle-free, unattended, and fast.
