Manual Single‑Point Drain System

BOAT IN THE WATER

1. Close the seacock (if equipped) or remove and plug the water inlet hose.
2. Rotate the blue handle counterclockwise until it stops (approximately two turns). The
red on the handle shaft indicates that the drain system is open. Do not force the handle
as this will create new threads.
3. Immediately remove the blue drain plug from the side of the thermostat housing. This
must be removed within 30 seconds to properly vent the cooling system.
