- the cylindrical main part of the housing base body 12 has in plan view a circular outer periphery 125 and a circular inner circumference or a circular inner side 126.
- annular mounting portion 13 of the housing base body 12 is above the Circumference distributed at regular intervals a plurality of circular openings 127 provided, can be passed through the screws for screwing to the hull 60.
- the inside cylindrical main part 128 of the case main body 12 also has a plurality of screw holes 129 distributed around its circumference at regular intervals.
- FIG. 5 shows a section along the section line BB from FIG. 3.
- the screw or blind hole 129 is a depression in the upper end face 121 of the cylindrical main part 128 of the housing base body 12.
- the opening 127 is continuous through the fastening section 13 educated.
- the width of the downwardly projecting flange 124 corresponds approximately to a quarter of the total width of the main part 128 of the housing base body 12.
- the height of the flange 124 corresponds approximately to one seventh of the height of the main part 128.
- a chamfer 1261 extending inwards from below is provided in the upper end region 1261.
- Fig. 6 shows a perspective view of the housing cover 1 1 with an attached annular disc 32
- Fig. 7 shows a section through the housing cover 1 1.
- the housing cover 1 1 has an inner opening 1 12, which is circular in cross section and formed to the passage of the rudder stock 54.
- the housing cover 1 1 is formed in the manner of an annular perforated disc, wherein it has in its outer, lower edge region downwardly circumferentially arranged projecting protrusion region 1 13.
- In the supernatant region 1 13 are circumferentially distributed screw or blind holes 1 14 for the preparation of screw with screws 321 arranged.
- the annular disc 32 is flush and is secured by means of screws 321 on the housing cover 1 1.
- a recess 1 151 is provided, which has a U-shaped outline in cross section.
- a (feather) spring (not shown here) is provided, which is designed to engage in the recess 151 in the sense of a driver. In this respect, this causes the housing cover 1 1 rotates with the rudder stock 54.
