SERVICING YOUR OUTBOARD MOTOR
4. Clean the oil filter mounting base,
and coat the rubber seal of the new
oil filter with clean engine oil.
Use only a Honda Genuine oil filter
or a filter of equivalent quality
specified for your model.
Using the wrong filter, or a non-
Honda filter which is not of
equivalent quality, may cause engine
damage.
5. Screw on the new filter by hand
until it contacts the engine, then use
a suitable tool to tighten the filter
an additional 7/8 turn.

7. Start the engine and check for leaks
(be sure the water level is at least 2
inches (5 cm) above the
antiventilation plate).
If you are changing the oil filter
while the outboard motor is out of
the water, use commercially

available ear muffs and water hose
to supply water.
Running the outboard motor
without sufficient cooling water
will damage the water pump and
overheat the engine.
8. Stop the engine, and check the oil
level as described on page 80. If 
necessary, add oil to bring the oil
level to the upper limit mark on the
dipstick.
