Power Trim pump. Oil level
SX and DP-S drives
At the beginning of each boating season, check the
oil level in the reservoir as follows:
Trim the drive in as far as possible. Check the oil
level is between the MAX and MIN markings on the
oil reservoir. Top up if necessary using ATF oil.
Cleanliness is extremely important, no dirt must get
into the drive when topping up with oil.
If the system has been drained, fill with new oil and
trim the drive in and out 6 – 10 times to vent the
system. Check the oil level and top up if necessary.
Trim fin. Adjusting,
SX drive
NOTE! The DP-S drive has no trim fin.
C
No adjustment is required if the boat has power stee-
ring. If there is no power steering the trim fin must be
adjusted depending on propeller rotation. With a left-
rotating propeller the measurement (A) is 83 mm
D
(3.3 in)(B= 5 ° ). With a right-rotating propeller the me-
A
B
°
asurement (C) is 57 mm (2.2 in.)(D = 30 ). These set-
tings apply to all installations, even twin drives. Tigh-
ten the trim fin using 38-44 Nm 28-32 ft.lbs.). Right or
left-rotating propeller: See under heading "Propel-
lers".
Twin installations,
DP-S drive
Duo Prop drive units have counter-rotating
A
propellers. There is no need to alter the direction of
rotation of the drive units in twin installation.
In Duo Prop drive unit twin installation the drive unit
must be adjusted so operation is free from cavitation.
To adjust, measure the distance (A) between the
center line of the two transom shields. Adjust tie bar
so the distance (B) between the center of the
B
cavitation plate is equal to distance (A).
