the coupling grubscrews 22. Fix the motors in place
using the screws 14 and washers 15.
- Fit the suppressor capacitors 16 and 17 to the motors,
and wire them together using the cables 18 and 19. Fit
insulating sleeves on the capacitor pins before fitting
them (Fig. 17). Solder the connectors 20 to the motor
wires. Fit the shaft couplings 21 and the grubscrews
22 - Figs. 16 - 18.
- Carry out a test-run of the motors; they must rotate in
opposite directions (contra-rotating propellers). If this
is not the case, reverse one motor by swapping the
wires over at the motor terminals.
- File the underside of the lubricating tubes 23 to fit on
the stern tubes 4, and solder the parts together. Drill
a 3 mm Ø hole into the stern tubes, working through
the lubricating tubes. Carefully remove all the drilling

- Fit the washers 32 and the bushes 33 on the rudders
31, slide them into place and engage them in the bot-
tom bushes 29 - Fig. 25.
- Fit an O-ring 34, a second washer 32 and a tiller
assembly 35 - 37 on the top end of each rudder shaft -
Figs. 26 and 27.
- Check the alignment of the entire power system and
rudder system inside the hull: the shafts and propel-
lers must rotate freely and smoothly. Ensure that the
rudders are exactly parallel when viewed from the
side and from underneath. The propeller shaft tubes
must not be under stress. If necessary file out the 6

swarf - Fig. 19.
- File a flat section in the propeller shafts 24 to accept
the coupling grubscrews 22.
- Fit the collets 25 / 26 and engage the propeller shafts;
don't tighten the grubscrews at this stage.
- Fit the locknuts 27 on the propeller shafts and run
them to the end of the threaded section. Adjust the
position of the propeller shafts so that they rotate free-
ly. When you are satisfied, tighten the grubscrews 22
and position the collets 25 - Figs. 20 - 22.
- Screw the propellers 28 on the propeller shafts, and
tighten the locknuts 28 against them.
- Attach the bottom rudder bushes 29 to the Kort nozz-
les using the countersunk screws 30 - Fig. 23.

mm holes in the shaft fairings until this is the case. It
may be necessary to file back the central Kort nozzle
strut slightly - see arrow in Fig. 23.
- Glue the speed controller support assembly against
the keel in-fill piece, and glue the motor bulkhead to
the speed controller support. Glue the Kort nozzles in
the hull, and the stern tubes in the shaft fairings.
- Check that the rudders rotate smoothly, but without
any tendency to slip out of the bottom bushes 29.
Glue the rudder bushes in place.
- Sand back the keel in-fill piece to the point where it
ends at the same height as the Kort nozzles inside the
