ABSTRACT:
Disclosed herein is a tie bar for connecting a pair of marine propulsion devices which are respectively pivotable about spaced vertical axes for steering and about a common horizontal axis for tilting, which tie bar includes structure for selectively affording axial extension of the tie bar in response to tilting movement of one of the propulsion devices relative to the other of the propulsion devices and for preventing axial extension of the tie bar during normal steering movements.
