Remove prop shaft from stern tube, insert stern tube in hull so that it protrudes from hull
by approximately 3 mm.
Insert prop shaft in stern tube, install spacer and secure with M4 nut.
Temporarily install prop (diameter 50 mm) on prop shaft. There should be a distance of
about 5 mm between rudder and prop hub.
From the aero-naut range of
accessories select a motor coupling
which fits your prop shaft and motor
shaft diameters.
Note:
Illustration shows installation
of aero-naut spring coupling.
Place sub deck assembly in hull and position carefully. If necessary, adjust contour of
frames until frames fit hull and prop shaft moves freely and without binding.
Note:
The tab at the bottom of frame 24 is used to position the sub deck assembly.
Adjust frame until tab fits keel perfectly and frame rests against hull. With a soft pencil
mark position of sub deck assembly in hull.
When a perfect fit is achieved, glue prop shaft into hull with a liberal amount of Stabilit
Express. To guarantee exact alignment of prop shaft, connect motor to prop shaft until
glue has cured completely.
Then glue sub deck in place with Stabilit Express and leave to cure.
