OIL LEVEL INSPECTION
Start the engine, let it warm up to the normal operating
temperature, and stop the engine.
Place the outboard motor in the vertical position (with
the engine level), and remove the engine cover.
Remove the dipstick [1], and wipe it clean with a shop
towel.
Insert the dipstick into the oil level pipe fully, then
remove it and check the oil level.
Check whether the oil is dirty or has a milky color.
Replace the engine oil if it is dirty (page 3-5).
If the oil has a milky color, check the gaskets and
replace them with new ones if necessary:
– Mount case gasket (page 13-4)
– Cylinder head gasket (page 14-22)
– Oil pump gasket (page 12-9)
– Oil case gasket (page 12-6)
If the oil level is low, remove the oil filler cap [1], and
add the recommended oil to bring the oil level up to the
upper level mark on the dipstick.
Check that the O-ring [2] is in good condition, replace it
if necessary.
Install the oil filler cap and dipstick.
