Catalina Owner's Manual - Chris Craft

Systems
Engine Warning System
There is no fire alarm or built-in fire extinguishing system associated with the engine. Coast Guard regulations
require an appropriate hand-held fire extinguisher be on board when operating the boat. Ensure your
fire extinguisher is current and capable of extinguishing any type of fire.
You should frequently check the fire extinguisher for the correct pressure. If the pressure is below specification,
have the unit serviced. You should also weigh the cylinder (less the bracket) for proper weight. If
the gross weight has deviated from the specification label, service or replace the fire bottle. Weigh the cylinder
at least twice a year.
Do not operate an engine if an engine warning indication has activated.
Correct the discrepancy before using the engine. Failure to
correct a malfunction may result in serious engine damage. DO NOT
try to correct the problem with the motor running, serious injury
may result.
If a low oil pressure warning exists, do not operate the engine any
longer than absolutely necessary. Serious engine damage may
occur.
The Catalina engine(s) have the following warning systems installed:
• Overheat warning
• Low oil pressure warning
If either of these conditions exist, the warning system activates and a buzzer sounds. Shut down the engine
immediately and investigate the cause of the malfunction. If the cause of the problem cannot be found and
corrected, contact the appropriate dealer for assistance.
Engine Overheat
Should the engine overheat the engine speed automatically drops to approximately 2,000 rpm. An overheat
warning indicator will illuminate or blink and a buzzer sounds.
On dual engine models should one engine overheat the affected engine slows down but the unaffected
engine also slows down, causing the warning indicator to illuminate and the buzzer to sound. To turn off
the warning system for the unaffected engine, shut down and turn off the main switch to the overheating
engine. This action cancels the alarm to the unaffected engine.
One of the primary reasons for engine overheating is lack of cooling water through the engine. Inspect the
cooling water inlet for debris and clogging. Clean as needed. If the cooling water inlet was clogged, allow
the engine to cool down before attempting a restart. If the engine still overheats, shut it down until the
cause of the malfunction can be discovered and corrected.
