UNDERWATER HARDWARE-SEACOCKS &
STRAINERS
Inspect the thru-hull seacocks before each outing. Make
sure the connections between the output hose and the
valve are tight. Look for water leaks around the area where
the valve and hull meet.
Every 30 days open and close each thru-hull valve several
times. This will guard against the valve seizing in the open
or closed position. Also, make sure the valve handle is
tightly fastened. Secure any loose valve handles.

Before servicing the sea water strainer make sure the
appropriate seacock has been closed to prevent water
entering the boat. If possible blow out the strainer basket
with compressed air or use a metal type brush to remove
any accumulated material from the screening material.
Make sure the strainer is aligned in the center dimple on
reinstallation.
Check all parts for wear and possible leaks including
any gasket surfaces. Do not overtighten the strainer
hold down fasteners which could cause strainer body
damage especiallyon the newer plastic versions. Use
original replacement marine parts only. After all parts are
reassembled open the seacock and check for leaks.
Notice there is a drain hole in the bottom of the strainer
body.
