Lubrication. Primary shaft bearing
1. Remove the drive from mounting fork.
2. Grease the primary shaft bearing via the nipple (1)
using a grease gun. Use an EP wheel bearing grease.
Press in grease until it is forced out of the bearing.
If the old grease indicates water contamination the
bearing must be inspected and replaced if
damaged.
WARNING! Removal of the drive requires special
knowledge and tools. A falling drive can cause
serious personal injury. Please contact your near-
est authorized Volvo Penta dealer for assistance.
Twin installations, DP-S drive
Duo Prop drive units have counter-rotating 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 cent-
er 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).
Trim fin setting, SX drive
No adjustment is required if the boat has power steer-
ing. If the boat is not equipped with the power steering
the trim fin should be set depending on the propeller
rotation.
WARNING! Immobilize the engine before starting
work.
The following initial setting applies for both double
and single installations:
With a left-rotating propeller (B) the measurement D is
83 mm (E = 5°). With a right-rotating propeller (A) the
measurement F is 57 mm (G = 30°). Tighten the trim
fin using 38-44 Nm.
If the steering wheel still feels heavy further adjustment
may be required.
