A critical element of winterizing and off season maintenance, engine flushers wash away contaminants from your lower unit, inboard cooling system, and remove salt and mineral build-up to prevent scaling and corrosion. Moeller Flushrite boat motor flushers make flushing marine outboard, stern drive and inboard engines easy. Simply connect a garden hose to the flusher and attach it to the water intake.

Rubber cups slip over side water inlets on most inboard and outboard lower units, channeling water into the engine cooling system. Telescoping tube makes flushing inboard engines and other hard to reach systems easier.
