An apparatus for steering control of water craft by operator body motion commands. The craft is powered by an outboard motor having a first vertical axis. The water craft has a swivel seat co-axially mounted to first and second swivel bodies permitting rotation of the seat about a second vertical axis. There is a first control member-mounted between the seat and the first swivel body and a second control member mounted between the first and second swivel bodies. A connecting member connects the second control member to the outboard motor so that when a pin couples the first and second control members together the apparatus is engaged and swivel seat is able to transmit body motion steering commands via the connecting member to the outboard motor.
