7.5 Stator / impeller blades are bent or
broken (low thrust or no thrust at all)
1. Protective lamellas (front)
2. Electronics box
3. Motor
4. Impeller wheel with impeller blades
5. Stator

The stator and defective impeller blades can be re-
placed separately. To do this, proceed as follows:
1. Remove the jet channel cover as described in Chapter
7.4.
2. Remove the stator, and replace it if necessary.
3. Unscrew the impeller disc on the impeller wheel to
replace individual impeller blades.

7. Put the jet channel cover back on, and fasten it in
place. Use the Allen key (size 5) to tighten all twelve
attachment screws (approx. 5 Nm; torque wrench rec-
ommended). Before fastening the jet channel cover in
place, ensure that the stator is seated properly and
locked in position.
The protective lamellas are attached to the SEA-
BOB housing and should never be removed. Be-
fore fastening the jet channel cover in place, check that
the protective lamellas are seated properly and securely.
Note:
Removing the protective lamellas would not en-
hance the thrust of the craft.
8. Turn the SEABOB back over, and check all components
once again to ensure that they are seated properly
and securely.
9. On models with Accumulator Change System (SEA-
BOB CAYAGO VX2 and SEABOB CAYAGO F7 models),
reinsert the accumulator box ACS, switch on the SEA-
BOB with the charger (see Chapter 5.4.5 "Off mode")
and check that the motor and impeller can move
freely.
Never run the motor out of the water for longer
than approx. 10 seconds. The seals of the motor
and the hard-coated motor shaft are designed exclusive-
ly for use in the water. Operation out of the water can
cause overheating due to the lack of water to cool the
device, thereby causing irreparable damage to the seals
and motor shaft.
