Perko FlushPro

Simplify routine freshwater flushing and winterizing antifreeze draw for inboard engines with the new FlushPro from Perko. Saltwater, silt, and zebra mussels shorten the lifespan of inboard heat exchangers and engine blocks. Traditional freshwater flushing or winterizing requires closing seacocks, loosening hose clamps, and manually disconnecting raw-water plumbing, a process that risks intake failure and leaks. Perko Flush Pro valves eliminate hose teardown entirely. Spliced permanently into the intake line, the Flush Pro features an internal check valve activated by dockside hose pressure. Connecting a garden hose automatically shuts off the hull intake to draw freshwater directly into the cooling system, even while afloat. For end-of-season lay-up, inserting the included winterizing adapter allows the engine to pull marine antifreeze directly from a jug into the cooling circuit - making the whole process a snap.
