Seacocks And Thru-Hulls; Drain Plugs - Chris-Craft 2014 36 RH Corsair Owner's Manual

Systems

Seacocks and Thru-Hulls

Each boat has thru-hulls associated with it. Depending upon the model and engine configuration of your
boat, it may also include one or more seacocks which allows for raw water engine cooling.
The appendix provides CAD drawings for each boat model, including seacock and thru-hull locations. It
is your responsibility to become familiar with those drawings appropriate for your boat.
Most seacocks are equipped with a shut-off feature, normally in the form of a ball-valve. Each seacock
should be exercised periodically to ensure proper function and to prevent corrosion accumulation.
A seawater strainer, attached to the seacock, protects the system from foreign objects that may enter the
seacock. The strainer should be periodically cleaned and inspected for effective operation.

Drain Plugs

CAUTION
Ensure you re-install the drain plug BEFORE putting the boat back into the water.
Failure to do so will result in flooding of the engine compartment.
Garboard Drain plugs (Figure 3-6) allows water to drain from the boat when trailered. After the boat
is pulled from the water, open the drain plug so as to allow accumulated water to drain. When feasible,
and if applicable, rinse the area with fresh water to prevent salt buildup and corrosion.
If the boat will not be operated for more than a month, the engine should be prepared for extended
storage as outlined in the Owner's Manual, Maintenance, and Warranty manual.
