Advantages of the DIREKT coupling flanges or Gundert-Power-Direkt drive systems compared to all other shaft systems available on the market

- inexpensive
- easy replacement or repairs to the engine. Even if it is difficult to get to the engine screws because the rear or fittings are too tight or the engine screws are difficult or impossible to reach. With this drive system you only work from above.

Assembly of the power direct shaft system

1. Drill out the shaft passage at the stern and push through the shaft system. The shaft tube should protrude at least 1-2mm so that the thrust washer is not stuck together.
2. Make a support out of wood, GRP or similar and fit it into the fuselage under the coupling flange.
3. Place the two drive-in nuts on the support and tighten the coupling flange from above using the M3 screws provided.
    If necessary, drill holes for the screws in the base.
    Glue the support in the fuselage.
4. Glue the drive-in nuts to the support with 2-component adhesive. Lightly grease the screws to prevent them from sticking.

Dismantling the motor
Unscrew the screws from the drive-in nuts. Loosen the two M3 threaded pins in the flange and the coupling.
Remove the motor with the coupling flange and coupling from the pipe.
Now you can easily work on or change the engine. The assembly is carried out in reverse order. The previous installation position is reached again by the glued drive-in nuts.
Important: Do not use frames that are not in the boat to install the coupling flange. Glue an extra pad into the boat. Otherwise you will lose the advantages of simple dismantling. Assembly or disassembly from above is then no longer possible.
