Fuel System
Top off your fuel tanks with No.2 diesel fuel. Fuel additives such as Sta-Bil and BioBor should
be added at this time to control algae and condaion the fuel. Care should be taken that the
additives used are compatible wah the primary fiher/water separator used in the system. Change
the element in your primary fuel Mer/water separator, H the fuel system contains one, and
clean the separator sediment bowl.
Change the fuel filter element on the engine and bleed the fuel system, as needed. Start the
engine and allow it to run for 5 - 10 minutes to make sure no air is left in the fuel system.
Check for any leaks that may have been created in the fuel system during this servicing,
correcting them as needed. Operating the engine for 5-10 minutes will help allow movement
of the treated fuel through the injection equipment on the engine
Raw Water Circuit
Close the through-hull sea cock. Remove the raw water intake hose from the sea cock. Place
the end of this hose into a 5-gallon bucket of clean fresh water. Before starting the engine,
check the zinc anode found in the primary heat exchanger on the engine and clean or replace
a as required, and also clean any zinc debris from inside the heat exchanger where the zinc
anode is located. Clean the raw water strainer, H one is installed, in the inside of the hull.
Start the engine and allow the raw water pump to draw fresh water through the system. When
the bucket is empty, stop the engine and refill the bucket with an antifreeze solution slightly
stronger than needed for winter freeze protection in your area.
Start the engine and allow all of this mixture to be drawn through the raw water system. Once
the bucket is empty, stop the engine. This antifreeze mixture should protect the raw water
circuit from freezing during the winter lay-up, as well as providing corrosion protection.
Remove the impeller from your raw water pump (some antifreeze mixture will accompany it, so
catch it in a bucket). Examine the impeller. Acquire a replacement, if needed, and a cover
gasket. Do not replace the impeller (into the pump) until recommissioning, but replace the
cover and gasket.
Intake Manifold and Through-Hull Exhaust
Place a clean cloth, lightly soaked in lubricating oil, in the opening of the intake manifold to
block the opening. Do not shove the cloth out of sight. (If it is not visible at recommissioning,
and an attempt is made to start the engine, you may need the assistance of a servicing dealer.)
Make a note to remove the cloth prior to start-up. The through-hull exhaust port can be blocked
in the same manner.
