and remove the locking screw (4), tab washer and
nut (6).
Reverse gear: Remove the nut (7), washer (8) and

(drive). Clean and lubricate as described.
Installing
1. Reinstall the spacing sleeve (drive) and the
propeller hub on the shaft.
2. Drive: Install the nut (6). Place a propeller blade on
the hub and place a wooden block between the
propeller blade and the underwater hull. Tighten
locknut to 70 Nm.
Reverse gear: Install the washer (8) and tighten the
nut (7) to 220 Nm. Apply thread sealant to the
locking screws (9). After the locking screws have
been tightened apply thread sealant to the screw
heads as well.

and tighten the locking screw (4) to 20 Nm and
bend one of the tab washer tabs to the screw head.
IMPORTANT! The tab washer (3) must be re-
placed if necessary. Use only Volvo Penta ori-
ginal locking screws (4).

push in the stud (1) in such a position so the
groove in the stud is exactly centered in the hole
for the locking screw (5). Apply thread sealant to
the locking screw and tighten to 10 Nm.

the blades are at the same angle to the propeller
shaft and that they move easily.
