4. MAINTENANCE AND INSPECTION

EN
(Battery fluid tends to evaporate in
high temperatures, especially in sum-
mer. In such cases, inspect the battery
earlier than specified.)
2. If the starter rpm is too low and the en-
gine cannot be started, measure the
specific gravity of the battery with a hy-
drometer.
When the specific gravity of the fluid is
over 1.27(at 20°C)[68°F]), it is fully
charged.
Fluid with a specific gravity of below
1.24 needs charging. If the specific
gravity cannot be raised by charging,
the battery must be replaced.
The capacities of the standard al-
ternator and the recommended bat-
tery assume only the power
necessary for regular operation.
If the power is also used for inboard
lighting or other purposes, the gen-
erating and charging capacities
may be insufficient. In such cases,
consult your Yanmar dealer or dis-
tributor.
4.3.3 Inspection Every 100 Hrs (or
six months).
(1) Replace the Sail Drive Oil
Refer to the operation manual of the
sail drive for the procedure of the oil
replacement
4.3.4 Inspection Every 150 Hrs (or
one year).
(1) Replace the Engine Oil
Refer to 4.3.1(1).
(2) Replace the Marine Gear oil
Refer to 4.3.1(2).
4.3.5 Inspection Every 250 Hrs (or
one year).
(1) Replace the Fuel Tank
Refer to 4.3.1(4).
(2) Replace the Fuel Filter
When there is dirt in the fuel, the filter
becomes clogged, and the fuel will not
flow easily. Check and replace the el-
ement.
1. Close the fuel cock.
2. Remove the filter case by loosening
the retainer ring (Turn counterclock-
wise) with the filter wrench.
3. Pull the element out from the bottom,
and replace with a new one.
4. Clean the inside of the case thorough-
ly, put on the O-ring, and close with
the retainer ring. (Turn clockwise:
Tightening torque:12 Nm (106 lb-in)
5. Air will enter into the fuel system when
the filter is disassembled, and should
be vented. (See 3.3.2(4))
