Seacocks And Thru Hulls; Garboard Drain Plug - Chris-Craft 2015 21 Carina Owner's Manual

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. Because the IB model
has no sterndrive, this 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 these drawings.
The seacock is equipped with a shut-off feature,
normally in the form of a ball-valve. The 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.

Garboard Drain Plug

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.
