IMPORTANT! The hydraulic pump must be in-
stalled vertically, as reflected by the picture.
16. Remove the oil filler/indicator plug to check the oil
level. Top up if necessary. Install the sterndrive in the
transom shield. Raise and lower the drive simultane-
ously to facilitate the topping up and to make sure
that the system is properly filled up. The oil level
should be level with the oil filler hole. Use the same oil
quality as for the engine or ATF oil. See below.
17. Oil level, hydraulic pump – power trim:
Trim in the drive as far as possible. Check that the oil
level is between the max and min. marks on the
reservoir. Top up if necessary with ATF oil.
NOTE! Early production drives were filled with engine
oil and have that recommendation in the Owner's
Manual. Late production drives have ATF oil filled.
IMPORTANT! We recommend the use of ATF
oil. Observe strict cleanliness so that dirt is not
drawn in by the oil.
ATF oil and engine oil must never be mixed.
If ATF oil is to be used, the engine oil must first
be drained from the system. If the system has
been drained, fill up with new oil and trim the
drive 6 to 10 times in and out to purge air from
the system. Check the oil level and top up if
necessary.
