Winterizing Raw Water Cooled Diesel Engines
Sten
L Drain crankcase and transmission and refill with fresh oil
as specified in owner's manual. Change oil filters.
2. Close seacock, remove raw water pick up hose from wa-
ter pump, attach a 4-foot length of hose to water pump and
immerse in a 5 gallon bucket of antifreeze solution. Remove
.- hose from engine or manifold that leads to exhaust elbow.
Attach about a 4-foot length of hose and immerse one end in
the bucket ofantifreeze solution. Start engine and run until
water begins to warm up (about 3 to 5 min.) and thermostat
opens. Stop engine. Replace hose that leads to exhaust el-
bow. Start engine and let run till water comes out exhaust
pipe. Stop engine, remove hose from water pump to bucket,
attach hose from seacock to water pump and tighten all hose
clamps. Note: This procedure bypasses the sea strainer
to prevent antifreeze from crystallizing sea strainer
which warranty will not cover.
3. Loosen water pump and alternator belts to lessen tension
on belts during winter.
4. Drain and clean all fuel filters and change elements, gas-
kets and seals. Bleed all air from fuel systems.
5. Pull compression release levers and turn engine slowly with
the hand crank. Slowly pour about 2 ounces of engine oil into
the intake pipe or manifold while hand cranking the engine.
DO NOT USE the starter to turn engine or serious engine
damage may result.

DEPARTURE FROM TIIE BOAT
The check list for leaving a boat trnattended is very impor-
tant because items overlooked oftenwillnot be renpmbered
until you are far fromthe boat and corrective actions are
impractical or impossible. Primary choices forthis list are
items relating to the safety and security of the unattended
craft --- turning offfuel valves, the proper settings for elec-
trical switches, pumping out the bilge and leaving the switch
on automatic (or arranging for periodic pumping out). Other
departure check list items are securing ports, windows,
hatches, and doors.
ROUTINE MAINTENANCE
Routine maintenancechecklists
should include items hsed
on how much the boat is used (usually in terms of engine
hours) and oncalendar dates (weekly, monthly, or seasonal
checks). Typical of the former are oil level checks and
changes, and oil and fuel filter changes.
On a calendar basis the lists should note such matters as
electrolyte levels in storage-batteries,
pressure gauges on
dry-chemical fire extinguishers, and all navigation lights.
Check the operation of automatic bilge alarms or pump
switches by running water into the boat. Periodically close
and open seacocks several times to ensure their free and
easy operation in case they are needed in an emergency.
Equipment and zupplies carried onboard for emergencies
should be inspected for any signs ofdeterioration.
