3. Impeller
3.1. Detachment
The boat must be lifted out of the water to remove the impeller. Before you can get to
the impeller, the reversing deflector, the steering nozzle and the stator must be removed.
See sections 4-6.
Before the rear end bearing can be disassembled, the reversing deflec
-
tor, the steering nozzle and the stator (see sections 4-6) must be remo
-
ved from the rear end of the jet. The boat must be out of the water.
Loosen the fastening screws of
the impeller and remove one of
the screws (figure 3.1-1).
Screw the screw into the threa-
ded hole (A) in the cone and
tighten carefully until the cone
loosens.
Take the bolt out of the threa-
ded hole and spin it loosely into
the free hole (B), i.e. back in its
original place.
Pull the impeller off the shaft.

The plastic cone may still sit tightly
on the shaft, but it can be loosened
by pushing a screwdriver into the
opening in the cone and forcing the
cone open. See figure 3.1-2.
3.2. Repair
Faults with the impeller that require repair are slight bending and cracking of the blades.
If a blade has been bent, carefully tap it back to its former position. Compare the posi-
tion of the blade to the other blades.
After straightening, make sure that there are no cracks at the bending point. If there are
cracks, the blade must be repaired by welding.
If a piece has broken off the blade, it can be repaired by welding filler metal in the
crack. However, we strongly recommend to exchange the whole impeller.
