3. Assemble motor with
cooling coil to motor mount. Handle the coil with care as it is made from
aluminium tube and is easily damaged. Slide the propshaft tube through the
hole in the hull and couple the shaft to the motor to trial fit the drive
assembly.(See separate instructions for drive shaft assembly.)
4. Once you have ensured that the motor and drive assembly fit into the
hull with the shaft aligned straight to the motor, the motor mount and
propshaft can be glued in place with thick cyano, having first roughened
the gluing area on the prop tube to ensure a good "key". The
propshaft should have l7mm of clearance between the hull and the shaft
centreline (see drawing.). Remove the motor and set to one side.
5. Place the rudder post in its hole and use a set square to get it
vertical in the boat. It is important that the rudder is vertical
otherwise the boat will have handling problems. When happy that the rudder
is positioned correctly, tack glue it in place. Offer up the ABS servo
mount/rudder brace to the transom side of the rudder post and glue it in
place to the floor of the boat, running a fillet of glue down each side of
the rudder post where it meets the servo mount.
6. Drill and file a 4 mm hole 55 mm forward of the transom and 5 mm
outside the left hand side inverted spray rail to accept the aluminium
water pickup which should be glued into the hull at an angle of approx 30
degrees. Cut off or file off any excess tube on the outside of the hull.
The water outlet should be glued in place near the motor on the side of
the deck.
7. Roughen the joining surfaces on the hull and deck with some 120 grit
sandpaper. Practice clamping the hull and deck together to make sure it’s
correct before glueing. The two halves can be joined with Stabilit Express
glue or Fusion glue or thick cyano. The 2 halves should be clamped
together using clothes pegs or bulldog clips, taking care not to distort
the boat. The flange can then be sanded down until it’s about 6-7 mm
wide.
8. Check the hatch line on the deck and cut around it using a NEW
Stanley knife blade or similar. Its possible to partly cut through and
crack it or just cut all the way through. Cut pieces of the excess flange
material removed from hull and deck to make strips to go inside the hatch
line on the deck to reinforce it. . The motor mount must be drilled and
filed to accept the motor and motor mounting screws. Then glue it in place
making sure the motor shaft and prop-shaft are aligned. The Servo should
be mounted near the back of the boat and connected to the rudder arm with
the supplied pushrod. The pushrod should be about 15mm long.
9. The hatch is sealed using waterproof tape. (sellotape diamond tape
or freezer tape)
