Definitions

  • FIG. 1 of the drawings Shown in FIG. 1 of the drawings is the lower unit of a marine propulsion device 11, such as an outboard motor or stem drive unit.
  • the lower unit includes a drive shaft housing 13 which can be mounted on a boat by suitable conventional means (not shown) for vertical swinging movement about a horizontal axis, as well as for horizontal swinging movement about a vertical axis for steering purposes.
  • the retainer 69 When the retainer 69 is moved from the neutral position of the rearward drive position, the retainer 69 is moved in the counterclockwise direction as shown in FIGS. 2 and 3, and causes the rearward drive rollers 65 to be drivingly engaged or wedged between the cylindrical surface 49 of the rearward drive bevel gear 25 and the axially extending edge portions 82 of the rearward propeller shaft flats 77.
  • the forward drive rollers 63 are similarly displaced in the counterclockwise direction but, because theiforward drive rollers 63 are angularly located to the right of the rearward drive rollers 65, the forward drive rollers 63 remain free of driving engagement with the forward propeller shaft flats 75.
  • the pin 351 engages the diagonal edge 359 or 361 of the applicable wing portion 355 or 357 to cause the retainer 269 to rotate toward the neutral position as the retainer 269 mvoes axially toward the neutral position, thereby discontinuing the driving engagement of the applicable rollers 263 or 265 between the propeller shaft 215 and the applicable driving bevel gear 223 or 225.
  • the retainer 569 is provided, between the forward and rearward sets of pockets 571 and 573, with an axially elongated slot 572 receiving a pin 574 which extends fixedly from the dog 537 and projects radially inwardly and through the slot 572 and into a camming recess 576 which is located in the propeller shaft 515 and which will be later referred to.
  • Axial actuator movement relative to the driving shaft 719 is effective to cause shifting in cooperation with separate forward and reverse cylindrical retainers or sleeves 801 and 803 (See FIGS. 15, 16, 18, and
  • the invention disclosed herein is also applicable to marine propulsion devices including an upright drive shaft having mounted thereon a pair of vertically spaced bevel gears which are both driven by an upper bevel gear suitably mounted for rotation on an axis transverse to the drive shaft axis.
  • the retainer and the associated rollers could be movable relative to the drive shaft between two or more positions affording forward drive, neutral, or rearward drive operation.
  • Various features of the arrangements shown in H68. 1 through 14 could be employed.
  • a marine propulsion device in accordance with claim and including means for displacing said roller from said position comprising a pin projecting from said propeller shaft, means on said roller displacing member cooperating with said pin for causing, in response to axial movement of said roller displacing member, angular shifting of said roller displacing member relative to said propeller shaft so as to displace said roller from said position of driving engagement, and said means for axially shifting said roller displacing member.
