Also, it is to be understood that the phraseology and terminoloyy employed herein are for the purposes of description and should not be regarded as limiting.

DESCRIPTION OF THE PREFERRED EMBODI~ENT

Illustrated in the drawings is a mounting arrangement 10 for an outboard motor 12 ~..

having a propulsion unit 13~ The propulsion unit 13 includes a lower unit 14 which comprises an emersible housing 16 with an electric motor (not shown) for driving a propeller 18 rotatably mounted on -the housing 16~ The lower unit 14 i5 mounted on the lower end of an elongated member or motor tube 20 which carries suitable wiring connecting the lower unit motor to a boat battery (not shown). Depending from the housing 16 is a skeg 22.
The outboard motor 12 also has an upper unit 24 which is connected to the upper end of the motor tube 20. The upper unit 24 includes a housing 26 by which the motor tube 20 can be selectively rotated for steering the lower unit 14 via a handle lS 28 formed as an integral part of the housing 26. In other embodiments, the motor tube 20 can be rotated relativè to the upper unit 24 by an electric motor (not shown) which is within the housing 26 and which is controlled by the outboard motor operator from a remote location.
As illustrated in Figures 1, 2 and 3, a support bracket 30 prevents lateral movement of the motor tube 20 relative to a boat hull or transom 31.
As illustrated in Figure 2, a bushing 33, which is held by the support bracket 30 and which loosely receives the motor tube 20, permits rotational and axial movement of the motor tube 20 relative to the support bracket 30.
As illustrated in Figure 2, ro~ation of 3Q the motor tube 20 during steering relative to the support bracket 30 is frictionally restrained by a steering friction member 34 mounted on the motor tube 20 above the support bracket 30. ~he steering friction member 34 is made from a non-galling ~ .

material, such a~ glass reinforced nylo~, and is releasably coupled to the support bracket 30 to prevent rota~ional movement of the friction member 34 relative ~o the support bracket 30 when the outboa~d motor 12 is in the operating position. The steering friction member 34 includes a suitable means, 6uch a6 a clamp 36, for selectively adjusting the rotational friction applied on the motor tube 20.
Fixedly mounted on the motor tube 20 above the friction member 34 is a 6top member 38 which engages the friction ~teering member 34 and limits the depth at which the lower unit 14 is submerged in the water. The stop member 38 preferably is mounted on the motor tube 20 for selective axial movement relative to the motor tube 20 so that the submersion depth of the lower unit 14 can be adju6ted. In the specific con6truction illustrated, the stop member 38 i8 in the form of a split sleeve clamp ~hich can be tightened into gripping engagement with the motor tube 20 by ~ightening a thread~d ~humb bolt 42.
As illustrated in Figure 1, fixedly moun~ed on the boat hull 4~ is a mounting bracket 46. The outboard motor 12 is supported from the mou~ting bracket ~6 by a support assembly 48 which provides pivotal mo~ement of ~he outboard motor 12 relative to the mounting bracket 46 between an operating position wherein the motor tube 20 is generally upright outboard of the boat and the lower unit 14 is ~ubmerged in the water (Fig. 1), and a storage position wherein the motor tube 20 is generally horizontal and the lower unit 14 is loca~ed ou~ of the wa~er and can be located inboard of the boat. While other 6uitable arrangements can be used je73 , in the specific construction illustr~ted, th~ support assembly 48 generally is arranged in the manner described in the U.S. Shi~anckas et al. Patent
3,870,258.
Means is provided for releaseably coupling the support bracket 30 with the stee~ing friction member 3~ tg prevent relative rotation thesebetween when the support bracke~ 30, and thus the o tboard motor 12, is in the operating position.
While other suitable arrangem~nts can be used for this ~urpose, in the specific construction illustratea in Figure 2, such means comprises providi~;g a slot or notch 66 in the lower portion 68 o~ th~ steering friction member 34 ~or fitting over a poction oE the support bracket 30.
Wh~n the propulsion unit 13 is in the operating position, the support assembly 48 yrevents further downward movement of the support bracke~ 30 ana th~ motor tube 20 is freely moveable, either axially or rotationally, relative to the support bracket 30. Thus, the steering friction bracket 34 is retained between the support bracket 30 and the stop member 38 by the weight of the outboard motor 12 bearing on th~ top or upper edge of th~ steering friction member 34 via the fixedly maunted stop m~mber 38. The opposite edges of the notch 66 in the steering friction mem~er 34 engages the opposite sides of the support bracket 30 to prevent rotation of the steering friction member 34 relative to the support bracket 30. Rota~ional movement of the motor tube 20, an~ thus the lower unit 14, relatlve to the suppor~ bracket 30 is frictionallY restrained by the friction steering member 34.

~, ' rl :~"

~Z~ 3 As illustrated in Figures 3 and 4, the support bracket 30 releasably holds the motor tube 20 to permit easy attachment and detachment of the outboard motor 12 from the mounting arrangement 10.
More specifically, the support bracket 30 comprises a clamp member 74, and a hinged member 73. The clamp member 74 is an elongated piece including a base portion 70 connected to the supported assernbly 48 and an end which includes a flat portion 86 which extends radially away from the mounting bracket 46. An indented portion 90 between the base portion 70 and the flat portion 86 is provided for receiving the motor tube 20 and bushing 33.
The hinged member 78 is an elongated piece including a first end 94 pivotally connected to the clamp member 74 between the base portion 70 and the indented portion 90. The hinged member 78 includes a second end with a flat portion 98 which extends away from the mounting bracket 46, and an indented portion 102 which is between the first end 94 and the flat portion 98 and which receives the motor tube 20 and bushing 33.
The support bracket 30 also includes means 106 extending ~etween the flat portion 86 of the clamp member 74 and the flat portion 9B of the hinged member 78 for releasably securing the flat portion 86 of the clamp member 74 to the flat portion 98 of the hinged member 78, so as to secure the motor tube 20 and bushing 33 between the clamp rnember 74 and the hinged member 78. The secùring means 106 comprises a thumb screw 110 threaded in a bore 114 in : the flat portion 86 of the clamp member 74 and received in a threaded bore 118 in the flat portion 98 of the hinged member 78. In another embodiment .--~
~2:2~)G~3 _9_ (not shown), the thumb screw 110 can be threaded in the bore 118 in the flat portion 98 of the hinged member 78 and received in the threaded bore 114 in the flat portion 86 of the clamp member 74.
The flat portion 98 of the hinged member 78 is spaced-apart from the flat portion 86 of the clamp member 74 when the motor tube 2~ and bushing 33 are received between the clamp member 74 and the hinged member 78, so that by adjusting the tension of the thumb screw 110, the frictional engagement between the support bracket 30 and the bushing 33 can be varied.
Various of the features of the invention are set forth in the following claims.
