Engine Oil - Honda Marine BF75A Owner's Manual

4. PRE-OPERATION
CHECKS
Engine Oil
Engine oil is a major factor affecting
engine performance and service life.
Running the engine with insuficient
oil can cause serious engine damage.
Recommended oil: SAE low-30
Use 4-stroke motor oil that meets or
exceeds the requirements for API
service classification SG or SH.
Always check the API SERVICE
label on the oil container to be sure it
includes the letters SG or SH.
Using nondetergent oil can shorten
the engine's service life, and using
2-stroke oil can damage the engine.
Inspection
1. Position the outboard motor verti-
cally, and remove the engine cover.
2. Remove the oil level dipstick and
wipe with a clean rag.
3. Reinsert the dipstick all the way in,
then pull it out and read the level. If
the oil registers near or below the
lower limit mark, remove the oil
filler cap and fill to the upper limit
mark with the recommended oil.
Do not overfill. Excessive oil can
damage the engine.
OIL FILLER
CAP
4. Reinstall the oil filler cap and tight-
en securely.
5. Install the engine cover and lock it
securely.
When the engine oil is contaminated
or discolored, replace with fresh engine
oil (refer to page 115 for oil
capacity, replacement interval and
procedure).
