The model has this vent is in the wrong location and orientation. Do NOT use the marked area on the port side Deckhouse roof suggested by the manufacturer.

Step 1 (Motor Unit Preparation).

Rotate the existing part so that the motor faces you. (The motor is the protruding `knob' with the small cross shape on the end of it opposite the curved downward duct). This is the correct orientation for the part. Now cut off the curved duct opposite the motor and file flat.

As you will be turning the vent in a different direction to the one the model builders had intended you may want to prep the motor unit as described in the Cowl Vents Attached to Motor Units section of the Vent Overview

Step 2 (Duct).

To create the new duct cut a rectangle of 2mm thick sheet styrene or one of the parts tabs from the sprue tree to approx. 7.5mm to 4mm and round the top corners with a file

Step 3 (Preparation for Assembly).

Cut out a rectangle as shown opposite.

There was a small circular duct that joined to the two parts together (see top diagram). To create this place the two parts together allowing the motor unit to sit 1mm over the inboard edge of the duct and put a mark on the back of the duct directly opposite the motor unit. Put the motor unit aside for one moment and using a 1.5mm bit drill a hole through where you put the mark.

Line the two parts up again and continue drilling into the back of the motor unit. Be careful not to drill too much or you will come out of the other side and wreck the vent.

Step 4.

Before gluing the parts together you have to reduce the height of the widest section of the duct by 1mm to allow for the raised platform that funnel no 1 sits on.

Step 5.

Dab a small drop of glue in the hole in the back of the motor unit and insert a short length of 1.5mm styrene rod. Allow to dry.

When dry put a drop glue into the hole in the duct and push the rod through the hole.

When dry trim the excess rod from the back of the duct and sand smooth.

Step 6 (Adding the Cowl Vent).

After making the few modifications suggested in the Cowls section of the Vents Overview glue the cowl vent on the port side of the motor unit facing the stern.

Step 7 (Location).

When placed correctly the vent's base should be slightly overlapping the port side face- of the large rectangular centre vent (H23B) in front of No. 1 funnel and the duct should cover the old Deck marking for the vent.

Note: If you are going to add the 7 poles and safety lines down each side of No. 1 funnel (See MISC section) the safety line will pass along the inside edge of the cowl over top of the motor housing.
