Engine flushers are used to wash away contaminants from your lower unit and inboard cooling system. It helps to remove salt and mineral build-up to prevent scaling and corrosion. This universal motor flusher makes flushing marine outboard engines easy. Simply attach a garden hose to the flusher and attach it to the water intake. The rubber cups slip over the side water inlets on most inboard and outboard lower units.
