Boat Maintenance Section 6
Sea Water Washdown System
Your boat might be equipped with a sea water wash-
down system. You must protect the washdown sys-
tem from damage caused by freezing temperatures.
Use the following steps to prepare this system for off-
season storage:
• Remove the cap from the hose outlet fitting
• Verify that the inlet seacock is in the
OPEN posi-
tion
• Run the washdown pump for approximately ten
seconds or until the water stops flowing
• Leave the inlet seacock in the OPEN position and
the hose outlet cap off during storage
Fresh Water System
Your boat might be equipped with a fresh water sys-
tem. You must protect the fresh water system from
damage caused by freezing temperatures.
Use the following steps to prepare this system for off-
season storage:
• Treat the fresh water holding tank with a non-toxic
antifreeze following the manufacturer’s recom-
mendations
• Run the treated water through all the outlets and
faucets to protect the under-deck plumbing
Hull Drainage
Remove the main hull drain plug. Open all internal
seacocks and drains. Verify that there is no debris
plugging any drain, seacock, or limber hole.
Store the boat with the bow higher than the stern to
promote adequate drainage.
Secure the main hull drain plug to the steering wheel
to alert personnel that the boat is in storage configura-
tion.
