COOLING SYSTEM
ZINC ANODE
A zinc anode, or pencil, is 'located in the raw water cooling
circuit within the heat exchanger. The purpose of the zinc
anode is to sacrifice itself to electrolysis action taking place
in the raw water cooling circuit, thereby reducing the effects
of electrolysis on other components of the system. The
condition of the zinc anode should be checked monthly and
the anode cleaned or replaced as required. Spare anodes
should be carried on board.
NOTE: Electrolysis is the result of each particular installation
and
vessel location; not that of the engine.

ZINC ANODES
If the zinc pencil needs replacement, hold the hex boss into
which the zinc pencil is threaded with a wrench while
loosening the anode with another wrench. This prevents the
hex boss from possibly tearing off the exchanger shell. After
removing the zinc, note the condition of it. If the zinc is in
poor.·condition, there are probably zinc flakes within the
exchanger. Remove the end of the heat exchanger and clean
the inside of all zinc debris. Always have a spare heat
exchanger end gasket
in case the present one becomes
damaged when removing the end cover. Replace the gasket
(refer to yoor engine model's heat exchanger end gasket part
number), a-ring, cover, and install a new zinc anode.
NOTE: The threads of the zinc anodes are pipe threads and do
not require sealant. Sealant should not be used as it may
insulate the zinc from the metal of the heat exchanger
housing preventing electrolysis action on the zinc.

NOTE: Operating in silty and/or tropical waters may require
thot a heat exchanger cleaning be peiformed more often than
every 1000 hours.

INSTALL THE FILTER CARTRIDGE INTO
THE HOUSING WITH THE SCREEN SIDE
OF THE FILTER FACING OUT OF THE
HOUSING. PRESS THE CARTRIDGE INTO
THE HOUSING LEAVING APPROX 1/8"
Description
A marine diesel engine running at high speed will typically
consume more than 6,000 cubic feet of air per hoor. Not only
must the engine room be well ventilated, the air flow into the
engine must be unrestricted.
Air Filter
The air filter cartridge prevents engine room dust and dirt
from entering the engine, it also improves oil consumption,
extends engine life, and quiets the engine.
Maintenance
The filter should be cleaned every 100 operating hoors. Tap
the cartridge on a flat surface to dislodge dirt or clean off
with compressed air. If the cartridge is badly contaminated or
. , oily, replace it.
IF THE FILTER ELEMENT IS CONTAMINATED
WITH DRY DUST OR DIRT, IT CAN BE CLEANED
WITH COMPRESSED AIR FROM INSIDE OUT
IF THE ELEMNET HAS ACCUMULATED
CARBON OR GREASE, IT MUST BE REPLACED.
