Propeller installation

Locking the propeller cone on sterndrives of earlier manufacture is done by a folding washer and on sterndrives 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 different from sterndrive model 290D ratio 2.15:1. The difference 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 eliminating 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 thorougly.

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.)
