ABSTRACT:
The transom mounted swivel bracket (16) of an outboard marine drive (10) has a clamp (36) with a pair of spaced parallel end tabs (40, 42) having aligned apertures (54, 56). A screw (58) has a leading end extension (68) extending through the apertures (54, 56) in the tabs (40, 42), and a shoulder (66) engaging one of the tabs and driving the one tab (40) toward the other tab (42) as the screw (58) is turned further into the swivel bracket (16), such that the clamp band (36) is tightened around the steering tube (20) to increase frictional steering resistance. The other tab (42) is held and retained by the leading end extension (68) which prevents deformation yielding movement of the other tab (42) into the tubular portion (18) of the swivel bracket (16).
