Definitions

  • ABSTRACT An inboard-outboard marine drive unit for boats wherein an outboard power leg is carried by an inverted yoke having a pair of downwardly extending, laterally spaced yoke arms receiving the power leg therebetween and a generally upwardly extending center post, the post being connected to the boat inboard of the stern transom.
  • the inverted yoke is steerab1e" in that steering of the power leg is accompanied by rotation of the yoke on its upwardly extending center post.
  • Raising and lowering of the outboard power leg for trimming, tilting and kick-up is by rotation of the power leg about a generally horizontal axis extending between the spaced yoke arms.
  • This invention relates to inboard-outboard marine drive units for watercraft. particularly boats, wherein an inboard engine has a rearwardly extending drive shaft coupled through universal joints to power transmission means in an outboard power leg to thereby drive a propeller carried at the lower end of the leg.
  • the outboard power leg is aft of the stern and is mounted for pivoting on two mutually generally perpendicular axes.
  • a main feature of the invention comprises the use of an inverted or downwardly disposed yoke member having an upwardly extending center post and downwardly extending laterally spaced yoke arms.
  • the outboard power leg is carried on a generally horizontal axis by the yoke arms whereas the yoke and outboard power leg together are connected to the boat by the upwardly extending center post.
  • the post provides a generally vertical axis for steering and is inside the boat where it is not exposed to water.
  • FIG. I is a partially broken away and partially sectioned port elevation of a boat with an inboardoutboard drive unit embodying the invention
  • FIG. 2 is an enlarged view of part of the port elevation of FIG. I primarily in section shown, among other features, the steerable inverted yoke and the double universal joints interconnecting the drive means between the engine and the outboard power leg; the upper portion of the outboard power leg is shown in a raised position in phantom lines.
  • FIG. 3 is a fragmentary view of the exhaust outlet for the unit taken in the direction of arrow 3 in FIG. 1.

  • FIG. 5 is an elevation showing the inverted yoke member by which the outboard power leg is supported and connected to the boat;
  • FIG. 6 is a perspective stern view showing the boat and outboard power leg of FIGS. 1 and 2, and
  • FIG. 7 is an enlarged view partially in cross section, taken generally along line 7-7 of FIG. 2, showing the pivoted connector attaching the forward ends of the hydraulic cylinders to the boat and showing in phantom the variable positions of the hydraulic cylinders when the outboard power leg is turned laterally to port and starboard for steering the boat.
  • the inboardoutboard unit includes outboard power leg 10 carried aft of stern transom I2 on a partially shown boat or other watercraft I4.
  • Outboard power leg 10 includes a propeller I6 carried by a horizontal propeller shaft 18 which is driven by power transmission means including vertical drive shaft 20 through a pair of bevel gears generally indicated at 22 to propel the boat.
  • Double universal joint 34 has its center substantially at the intersection of a steering axis and a tilt axis of outboard power leg 10. These axes are described further hereinbelow.
  • the drive connection between the horizontal drive shaft means 28 and vertical drive shaft 20 includes a pair of horizontal spaced beveled gears 36 and 38, one of which is a forward gear, the other being a reverse gear. Both are supported for rotation within suitable bearings on the upper end of shaft 20.
  • a drive gear 40 carried on horizontal drive shaft means 28 drivingly engages gears 36 and 38 and causes the latter to rotate in opposed directions in the well-known manner.
  • a clutch element, generally indicated at 42, is disposed between beveled gears 36 and 38 and is carried by shaft 20 and slidable axially thereon to selectively engage gears 36 and 38 to complete the drive connection between horizontal drive shaft means 28 and vertical drive shaft 20 to thereby drive propeller I6 in the desired direction.
  • Clutch element 42 also has an intermediate neutral" position between gears 36 and 38 in which position propeller 16 is rendered inoperative. Axial movement of clutch element 42 relative to shaft 20 is effected by projecting member 44 which may be actuated by means not shown. but typically a remote control arrangement in boat 14 as is known in this art. The particular drive connection and clutch arrangement described may be varied as its specific design is not critical to the invention.
  • the mounting means for outboard power leg 10, associated with the boat between the engine and outboard power leg comprises a one-piece casting 46 although it may comprise inner and outer separate pieces positioned on each side of transom l2 and bolted or otherwise fastened together.
  • Mounting means 46 includes an outer peripheral flange portion 48 which fits sealingly (seal 49) around transom opening 30 and may be fastened to transom 12 by a series of bolts as shown in FIG. 6.
  • Mounting means 46 extends through transom opening 30 and terminates interiorly of boat 14 and transom 12 in an upper rigid mounting portion 50.
  • the lower inner portion of mounting means 46 may include a lower mounting portion 52 for exhaust connection purposes.
  • Mounting means 46 will preferably be shaped to include a hollow or indented area 54 (best shown in FIGS. 2 and 6) in the upper portion 56 of house 24 when the outboard power leg I0 is raised. Such an arrangement also provides clearance for steering in the raised position.
  • Mounting means 46 may also carry a shaft support structure and seal arrangement generally indicated at 58 for supporting horizontal drive shaft means 28 in opening 30 of transom 12.
  • An annular flexible bellows 60 is disposed about double universal joints 34 and has its ends secured forwardly to support structure 58 and rearwardly to housing portion 32 as shown in FIG. 2.
  • Exhaust receiving means 62 is fitted to lower mounting portion 52 for receiving exhaust gases from engine 26. the interconnection therebetween not being shown for the sake of simplicity. Such arrangements are well known.
  • a flexible conduit member 64 interconnects fittings 62 and housing 24 of outboard power leg for conducting engine exhaust interiorly of housing 24 and out exhaust outlet 66, which is substantially at the water line when the outboard power leg is in its normal operating position and the boat is on plane.”
  • the exhaust arrangement for the unit is shown in detail in FIGS. 3 and 4 of the drawing.
  • Exhaust outlet 66 is closed by a flexible flapper member 67 which is normally closed to prevent the entrance of water into the unit. Due to its flexibility. it opens with exhaust pulses to allow the escape of exhaust gases to the water.
  • the unit may also include a trim tab 69 for off setting torque reaction and reducing steering effort.
  • the upper rigid mounting portion 50 of mounting means 46 pivotally supports an inverted yoke member 68 on a generally vertical axis to provide for steering movement of the outboard power leg in a lateral side to side movement.
  • Yoke member 68 is inverted or downwardly extending laterally spaced yoke arms 72.
  • Yoke member 68 is generally disposed inboard of transom 12 being mounted for rotation in upper rigid mounting position 50 by connection with upwardly extending center leg 70 and suitable bearing means and fastening means indicated at '74, 76 and 78 of FIG. 2.
  • the inboard pivotal support of yoke member 68 in upper mounting portion 50 provides the reguisite steering axis and steering movement of outboard power leg 10 which is carried by yoke arms 72 through its connection with housing portion 32 as best shown in FIG. 6.
  • This connection provides a generally horizontal axis extending through yoke arms 72 at 80.
  • Any suitable pivotal connection means may be utilized to establish the connection between housing portion 32 and yoke arms 72. Carried as described above. it can be seen that there is provided a steerable yoke member fitted inboard the boat in a compact manner.
  • Steering is provided for by means of tiller arm 90 which is connected to the upwardly extending center post 70 of yoke member 68 such that lateral movement of tiller arm 90 causes yoke member 68 to pivot in mounting portion 50 thus turning yoke 68 and moving outboard power leg 10 in a rotary steering movement, i.e., a lateral side to side movement.
  • Remote control mechanisms and/or power steering mechanism may be attached to tiller arm 90 to allow steering to be accomplished from other locations in the boat remote from the tiller arm. Such arrangements are well known in the art and need not be described herein.
  • a pair of extendable/collapsible hydraulic cylinders 82 and 84 are attached to each side respectively of power leg 10 and to boat 14.
  • cylinders 82 and 84 are pivotally connected to support 86 which is itself pivoted for turning at 88 on substantially the same axis as post 70 of yoke member 68.
  • Such an arrangement provides for the maintenance of the same relative position of the hydraulic cylinders 82 and 84 as outboard power leg 10 is turned through its various steering movements.
  • the hydraulic cylinders can assume varied positions shown in phantom depending on the extent of the steering movement.
  • Such cylinders can be readily designed to provide for trimming. tilting and/or kick-up and such design details do not provide any part of this invention and need not be described herein since such matters are well known in the art.
  • support 86 may include a pair of spaced lateral side members 92 and 94 (best seen in FIGS. 1 and 7) for slidably receiving outboard power leg housing 24 therebetween to provide lateral support therefor due to side loading of the unit.
  • the extent of the engagement provided by the side members may be varied by changing their size both overall and length.
  • an inboard-outboard marine drive unit for boats having an inboard engine connected to an outboard power leg through drive shaft means and universal joint means, the improvement comprising a yoke member having a generally upwardly extending center post directed oppositely from generally downwardly extending laterally spaced yoke arms.
