Abstract
The new tilt steering mechanism includes a housing having a tower and a pair of C-shaped clamps comprising a locking apparatus fixed with respect to the tower. Each clamp has a locking quadrant formed by alternating ridges and grooves. A swivel bar extends along a swivel axis and is trunnion-mounted for pivoting movement with respect to the tower and the clamps. An annular, ring-like locking device is mounted on the swivel bar for movement therealong and is spring biased toward the clamps. Such locking device includes a pair of wedge-shaped locking members for selectively engaging grooves in respective quadrants on the clamps. Other features for excluding dirt from the mechanism and, in the case of a mechanism used to drive a pump and steer a boat, for driving the pump and checking oil level are also disclosed.
