Exhaust
The exhaust system is used to remove engine exhaust fumes. To ensure that your boat’s
exhaust system is working correctly, it is important that you inspect for exhaust leaks.
The following information will allow you to check these systems. Keep in mind that you
will be checking engine while turned on, and that you will need to take safeguards against
getting yourself or others caught in the moving parts. Use extreme caution while
performing this task.
•
Turn engine off and disconnect the engine safety switch. Be sure the throttle
shift control is neutral. The engine must be cool.
•
Open the engine and visually check the exhaust system from the engine to the
transom for obvious damage.
•
Re-install engine safety switch and start the engine with engine compartment open.
Check hose connections between the exhaust manifolds and the muffler for leakage.
•
If leakage is apparent, tighten the hose clamps, being careful not to crimp the hose.
See your Malibu dealer for parts and or service.
Ventilation
The ventilation is used to remove potentially hazardous accumulation of explosive vapors
from the bilge areas of your boat’s hull and engine compartment. Therefore, proper
ventilation is essential to the safety of the boat and persons in or around the boat structure.
Your boat is equipped with a ventilation system that will ensure complete removal of these
dangerous fumes. However, it is your responsibility as the operator of the boat to ensure
these systems are working efficiently. The boat’s primary source for expelling fumes from
the boat is the blowers located in the bottom of the bilge and at the transom venting points.
See Section 2, page 2-1.
Your boat is also equipped with a natural air-intake that forces air through a venting system
on the deck of your boat, and channels air from the bilge to the transom vent.
Cooling
Most boats will be cooled with a continuous intake of lake water circulating it around
engine components.
Closed Cooling System
If your boat is equipped with an optional closed cooling system, you will need to maintain
correct fluid levels.
•
Open engine compartment and remove reservoir cap.
•
Ensure coolant is to the top of the reservoir filler neck.
•
Use Sierra Anti-Freeze
