4S: Sea Strainers & Through-Hulls
4S1: Sea Strainer Cleaning
and Seacocks
The sea strainers on this boat are secure and
reliable. They protect the engine, generator and
refrigeration cooling systems from water-borne
debris which might block internal equipment
passages. If a sea strainer needs cleaning (see
above regarding inspection) here is the procedure:
1. Follow the hose from the strainer to the valve
at the hull. On one side of the valve will be a
handle.
2. Turn the valve lever so it is perpendicular to
the thru-hull or hose (parallel to the hull).
3. Unscrew the top of the sea strainer (you
may need to use the fuel tank spanner from
the starboard salon door entry step). Then
remove the strainer by pulling it out the top of the assembly. Rinse the
strainer thoroughly and, if necessary, remove any debris from the glass
housing.
4. Reinsert the strainer, tighten the top cover and turn the valve back on (in
line with the thru-hull itself or its hose).
Failure to re-open the valves will overheat the engine or damage the
pumps!
This entire operation will take 5-10 minutes at most, and will assure you of cool
engines.
The main engine sea strainers are under the forward
engine room grid (which is easily lifted out).
