Propeller installation

Locking the propeller cone on sterndrives of earlier
manufacture is done by a folding washer and on stern-
drives of later manufacture by a locking screw through
the cone center.
Installing a 'long hub' type of
propeller (A)
1. Grease the propeller shaft with a thin layer of
grease.
2. Install the fishing line deflector (5).
3. Install the propeller.
4. Insert the plastic washer (3).
5. Install and tighten the propeller cone (1).
6. Install and tighten the center bolt, (6).
Installing a 'short hub' type of
propeller (B)
1. Grease the propeller shaft with a thin layer of
grease.
2. Install the fishing line deflector (5).
3. Install the propeller
4. Insert the plastic washer (3).

5. Install the spacer ring (2).
6. Install and tighten the propeller cone (1).
7. Install and tighten the center bolt (6).
NOTE! Sterndrive model 290B ratio 1.61:1 is differ-
ent from sterndrive model 290D ratio 2.15:1. The dif-
ference consists of propellers with long and short
hub respectively. See the picture!
NOTE! Short hub propellers (folding washer and cone)
will be replaced by long hub propellers (plastic washer,
cone, center bolt). When installing long hub propellers
on older sterndrives, the propeller shaft must be drilled
and tapped for use of cone with center bolt.
Use drill jigg 885149 to drill the propeller shaft elimi-
nating the need to remove the shaft from the drive unit
as follows:
1. Install drill jigg on propeller shaft.
2. Drill a 6.5 mm (0.255") hole to a depth of 20 mm
(0.787"). Use cutting oil to cool shaft. Clean thor-
ougly.
3. Use a 5/16"-18 UNC taps to thread shaft. Clean
thorougly.
4. Install propeller, plastic washer, cone and center
bolt. Torque: cone = 110 Nm (81 ft.lb.), bolt =
22 Nm (16 ft.lb.).
