DIREKT-Coupling-Flange maxi 700
Aluminium motor flange with built-in mounting flange provides a rigid connection between motor and shaft tube.
dissipate heat from the motor to the shaft tube
no loss of power due to misalignment
simple, quick assembly
The DIREKT coupling flange is made of aluminium. It has an angle that allows it to be installed in the boat. The coupling that connects the electric motor to the shaft runs in the flange.
There are spacer bushes if the shaft tube does not have the same diameter as the flange, e.g. no. 3.3268 from 9 mm to 8 mm Ø.
The shaft tube is clamped in the flange with a hexagon socket set screw.
After completing the assembly, a 2 mm Ø hole must be drilled for the connection nipple.
If the nipple is connected to the outside of the boat with a silicone hose, pressure equalisation can be created on the one hand and lubrication, e.g. shaft oil, on the other.

Advantages of DIREKT coupling flanges or Gundert-Power-Direkt drive systems over all other shaft systems available on the market
Easy replacement or repair of the engine. Even if you can't reach the engine screws easily because the rear or the internals are too tight or the engine screws are difficult or impossible to reach. With this drive system you only work from above.
Mounting the Power Direct Shaft System
1. drill out the shaft passage at the rear and insert the shaft assembly. The shaft tube should protrude at least 1-2mm so that the thrust washer is not glued.
Make a support of wood, GRP or similar and fit it under the coupling flange into the hull.
Place the two drive-in nuts on the support and tighten from above with the screws. If necessary, drill holes for the screws in the support.
Glue the support into the fuselage.
4 Glue the drive-in nuts onto the support using 2K adhesive. Lightly grease the screws to prevent them from sticking.
Disassembling the motor
Unscrew the screws from the drive-in nuts. Loosen the two M3 setscrews in the flange and the coupling.
Remove the motor with the coupling flange and coupling from the tube.
Now you can easily work on the motor or change it. The assembly is carried out in reverse order. The previous installation position is reached again by means of the glued drive-in nuts. Important: Do not use frames in the boat to install the coupling flange. Glue an extra underlay into the boat. The advantages of simple disassembly will otherwise be lost. Assembly or disassembly from above is then no longer possible.
