Abstract
A shock absorber adapted for use with the swivel bracket assembly of an outboard motor or the like, is disclosed, which swivel bracket assembly permits rotation of the motor to clear an underwater object if and when a boat strikes such an object. The shock absorber has a two stage operation in that it permits a swivel bracket assembly to rotate and provides a counterforce that is initially lower, and after some degree of rotation, preferably sufficient to have the drive shaft housing clear the object, provides a higher counterforce to continued rotation.
