Seawater Strainer - Mercury MerCruiser D2.8L D-Tronic Service Manual

SEAWATER COOLING SYSTEM
Seacock
If a seacock is being used, it must be installed between water pickup and seawater pickup
pump (or seawater strainer), to allow operator to shut off the seawater in case of a leak or
when boat is not in use. This will also allow the operator to flush or drain the engine, or clean
the sea strainer while boat is in the water. Install seacock in an area where it will be easily
accessible and support adequately to prevent hose fatigue.
To prevent restricting water flow seacock used must have an internal cross-sectional area
equal to or greater than hose.
Refer to Specifications.
