Engine Cooling System

FLOODING and SWAMPING HAZARD!
• Close the seacock(s) when leaving your yacht unattended for any length of time.

engines, and even sink your yacht.
SYSTEM DAMAGE HAZARD!

cooling system to reduce
engine temperatures.
• Open the seawater
intake seacock for each
engine before starting
the engines.
• Keep the seacocks
Open while the engines
are running.
• Check the cooling sys-
tem's seawater strainers
for leaks and debris
every time you use your
yacht.

tems section in Chap-
ter 6 of this supplement
for instructions about
cleaning the seawater
strainers.
