Through-Hull

（1） Sea Water Pump 

（2） Sea Water Strainer

Sea-cocks/Valves 

Sea-cocks are fitted to all the water intakes below water line, i.e. 

engine sea water cooling, generator, sea water deck wash down, 

etc. 

We recommend that all sea-cocks be left in the close 

position except when the system is in use. Sea-cocks should be 

returned to the off position after use and visually checked 

regularly for water tightness. 

For toilets that is situated bellow the waterline, get into the 

habit of systematically closing the seacocks after each use. 

CAUTION! 

Close all the seacocks when you leave the boat.  Make 

sure that all seacocks, which are not used, are closed before 

you put out to sea.
