As a result, reliable lubrication has been realized. 22 mm (0.87 in) 24 mm (0.94 in) S69W1210 1 Rotor 2 Embossed letters for identification Oil discharge volume 21.5 L (5.68 US gal, 0.22 Imp gal)/min...
  • Page 13 Features and benefits Although the main jet specification numbers of the F50 differed between cylinders, the F60 uses main jets with the same specification number for all four cylinders due to the change in shape of the intake silencer. S69W1230 È...

  • Page 14: Lower Unit

    INFO General information Lower unit Drive shaft The drive shaft has been machined to accommodate the high power output. The portion that mounts to the pinion gear has been machined with involute splines to increase durability. A section of the midspan of the drive shaft has been reduced to 14.4 mm (0.57 in) to prevent the drive shaft from breaking under impact loads.
  • Page 15 Features and benefits Forward gear bearing The size of the forward gear bearing has been increased to accommodate the high power output of the F60. With this increase, the coupling length of the forward gear has been extended as well. In addition, two grooves are provided on the forward gear for identification purposes.
