Exhaust System Routings
Engine Cooling System
The engine cooling system circulates water
through a heat exhanger on the engine to reduce
engine temperature.
•
Engine coolant (antifreeze) levels should be
checked at the engine-mounted expansion tanks
and at the coolant recovery bottles, located near
the engines.
•
The engine cooling system’s raw water strainers (located in the engine room) should be checked for leaks and
cleaned every time you use your yacht. For instructions on how to clean the strainers, see the Raw Water Strainer
section of this supplement.
•
Make sure both of the engine’s raw water intake valves (seacocks) are OPEN before starting the engines and
always keep them open anytime the engines are running.
Shaft Log Packless Sealing System
The shaft seal, which is part of the shaft log packless sealing system, is a maintenance-free, watertight seal that
doesn’t require packing or adjustments.
Rudder Stuffing Gland
The rudder stuffing gland is part of the assembly where the rudders emerge from the bottom of the boat. The shaft
stuffing gland should not leak any water. If a leak develops, it can usually be stopped by tightening the packing gland
nuts slightly. If stuffing gland leakage becomes excessive, replace the packing:
