Power Trim pump.Oil level
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.
Twin installations,
DP-S drive
Duo Prop drive units have counter-rotating propel-
lers. There is no need to alter the direction of rota-
tion 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 cavita-
tion. 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
cavitation plate is equal to distance (A).
Engine alignment
Engine alignment requires special tools and that the
drive unit be removed. This should be done when the
drive unit is removed for lubrication during off-sea-
son storage preparations. Because of the special
tools required, engine alignment must be performed
by a Volvo Penta dealer.
IMPORTANT Failure to check engine
alignment could result in premature failure of
engine coupler, universal joints, and gimbal
bearing.
