Owner`s manual
PREPARING ENGINE
FOR
SPRING SERVICE
Preparation of the engine should include all those items
of
maintenance necessary
to
permit satisfac-
tory operation of the engine. A properly serviced engine will give a
full season
of
carefree pleasure.
The amount
of
service needed will be determined by the storage procedure of the previous fall. Refer
to the section of the manual covering initial start up of the engine.
LUBRICATION SYSTEM:
1. Drain oil from crankcase using hand sump pump through the dipstick hole or oil drain hose
if
installed.
2. Install new oil filter.
3.
Refill crankcase with recommended grade and amount
of
engine oil. (Fill
to
upper or full
mark
on
dipstick).
Do
not overfill.
4. Be sure filler cap is secure after filling crankcase and that no oil leaks are apparent.
TRANSMISSION:
1. If transmission was completely filled for winter storage, some oil will have to be removed to
attain the correct
level in the transmission.
2. Check transmission
oil level according to specifications found in this manual.
3.
Be sure all plugs are secure and that no leaks are apparent. The drain plug should be
checked regularly.
CAUTION: DO NOT CROSS THREAD THE DIPSTICK THREADS
AS
IT MAY REQUIRE
HOUSING
REPLACEMENT.
SEA WATER COOLING SYSTEM:
1.
Remove front cover of pump
if
system was drained for storage. Inspect rubber impeller, light-
ly lubricate pump impeller, replace gasket and cover securely when inspection and lubrica-
tion have been completed.
2.
If impeller is not serviceable, see instructions covering the replacement of the sea water
pump impeller in the maintenance section of this
manual.
COOLING SYSTEM:
Model M-15
On Model 15, make sure all plugs and hoses are replaced and secure. Remove inlet hose on pump
and add about
314
oz.
of
lube oil. This will lubricate impeller when engine first starts until it picks up
sea water.
FRESH WATER COOLING SYSTEM: All Models Except M-15
1.
Inspect the heat exchanger and exhaust manifold for secure mounting and interior
cleanliness.
If system was filed with a 50/50 water and antifreeze mixture for storage, leaks
will be easier to detect than
if
the system was drained. The coolant should
be
relatively clear
and should be free of scale or other foreign particles.
2.
If system was drained and inspection is satisfactory, fill slowly with coolant and replace
pressure cap. Recheck coolant level after engine has run and reached operating
temperature. Use caution when removing cap when engine is hot,
you
could get burnt.
3.
Use antifreeze or rust preventative in system to prevent rust.
