Description
Flush-M Mercury 75-500hp (White)
Maintain your Mercury Four Stroke outboard with ease using the Flush-M Mercury (White), a permanent replacement for the OEM flush plug. Perfect for Verado, Pro XS, FourStroke, and SeaPro series (75–500 hp), this adapter streamlines engine flushing for single or multiple-engine boats.
The white Flush-M includes a 90° swivel elbow attachment for larger V8 Mercury engines, preventing hose kinks that can restrict water flow. It permanently replaces the OEM straight fitting and is designed for simple installation: remove the OEM plug, attach the Flush-M to the lanyard and 3/4" female hose receptacle, then secure with a 1/4-turn clockwise. To flush, connect a hose to the quick-connect cap, then replace the cap when finished.
