17. Disconnect the quick‑connect fitting and water hose from the flush socket on the engine
by pressing the release button on the flush socket.
18. Remove the quick‑connect fitting from the water hose.
19. Retain the quick‑connect fitting with the water hose end for repeated use by storing it
separately in a storage compartment on the boat for easy access.
IMPORTANT: Do not store the quick‑connect fitting in the flush socket on the engine. Doing
so would allow the seawater pump to suck air during engine operation causing an
overheating problem. Damages due to engine overheating are not covered by Mercury
MerCruiser Warranty.
