An outboard motor has a steering tiller handle assembly attached to the driveshaft housing and pivotally mounted within a swivel mounting bracket assembly. The swivel bracket assembly includes a split tubular element within which a split tubular section of the steering arm assembly is notably mounted and located encircling a tubular portion of the driveshaft housing. Upper and lower annular rubber mounts are located between the upper and lower end of the steering tubular section and the driveshaft housing. Each mount is formed with a first pair of axial slots formed in diametrically opposite sides of the mount and projecting inwardly from one end. A similar pair of slots offset by 90 DEG from the first set of slots extending inwardly from the opposite end of the annular amount. The driveshaft housing and the steering tubular section are provided with correspondingly offset projections adapted to mate with the slots in the annular mounting. Upper and lower sleeve bearings are located between the tubular section of the swivel bracket assembly and the steering arm assembly. The driveshaft housing is also employed as the exhaust passageway and includes a pair of openings aligned with the chamber to the steering assembly, the aft portion of which opens to the tubular section of the swivel bracket assembly. The outer wall of the swivel tubular section is provided with a generally U-shaped passageway with a closed end aligned with an exhaust opening and extending upwardly and then downwardly to discharge exhaust gases downwardly toward the water. |
