6.4.4 CHANGING POWERHEAD OIL BY EXTRACTION ON WATER
1 Position the outboard vertically. If your outboard has been tilted for storage or recently
operated, allow 20 minutes for oil to drain into the sump prior to commencing oil change.
2 Remove the upper cowling by opening the latches and lifting upwards.
3 Prepare a reversible extraction pump and one empty reservoir of at least 12L (12.7 US qt)
capacity to accept the used oil.
4 Remove the oil dipstick and wipe down with a lint-free cloth, then set aside.
5 Insert the extraction hose fully down the dipstick tube.
6 Activate the extraction pump.
NOTE
It may take some time for the extraction pump to start visibly moving oil through the hose,
especially when the oil is cold and viscous.
7 Continue running the extraction pump until oil stops moving through the extraction hose
and the tone of the pump changes. If the pump has extracted less than 10L (10.6 US qt),
check that the extraction hose is fully pushed into the dipstick tube. If necessary, remove
the hose, re-insert the dipstick fully then remove again and examine for any residual oil, then
wipe clean with a lint-free cloth.
NOTE
Your outboard(s) may have consumed some of its oil as part of normal
operation and the extraction method will always leave a small quantity
of oil behind in the sump.
8 Disconnect and set aside the extracted oil in the used oil reservoir. Dispose of this oil
thoughtfully (see section 1.3.1).
9 Remove and replace the oil filter following the procedure in section 6.3.6.
10 Fill a clean container with fresh oil in the same quantity as extracted from your outboard,
or 10.5L (11.1 US qt), whichever is higher.
