wherein the propulsion unit and the steering assembly are removable together from the swivel bracket by lifting the steering tube out of the hollow tube.
5. The outboard motor according to claim 4 , wherein the steering tube includes an inner tube and an outer tube on the inner tube, the inner tube configured to rotate in the outer tube when the propulsion unit is supported on and steered relative to the swivel bracket.
6. The outboard motor according to claim 5 , wherein the inner tube is fixedly coupled to the steering arm.
7. The outboard motor according to claim 5 , further comprising upper and lower bearings that facilitate rotation of the inner tube relative to the outer tube.
8. The outboard motor according to claim 4 , wherein the hollow tube has a seat and further comprising a fitting on the steering tube, the fitting being configured to rest on the seat when the steering tube is seated in the hollow tube.
9. The outboard motor according to claim 8 , wherein the fitting has a taper that guides the steering tube into a desired orientation in the hollow tube as the propulsion unit is installed on the swivel bracket.
10. The outboard motor according to claim 4 , further comprising pin that is movable into a locked position in which the steering tube is prevented from being removed from the swivel bracket and an unlocked position in which the steering tube is removable from the swivel bracket.
11. The outboard motor according to claim 10 , further comprising a handle for moving the pin into and out of the locked position.
12. The outboard motor according to claim 4 , further comprising a copilot configured to apply friction to the steering tube to resist steering of the steering tube relative to the swivel bracket.
13. The outboard motor according to claim 12 , wherein the copilot is movable radially inwardly and outwardly relative to the steering tube.
14. The outboard motor according to claim 12 , further comprising an actuator configured to vary the friction applied by the copilot to the steering tube.
15. The outboard motor according to claim 12 , further comprising a handle that is operable to vary the friction applied by the copilot to the steering tube.
16. The outboard motor according to claim 12 , further comprising a spring that biases the copilot towards the steering tube.
17. An apparatus for coupling an outboard motor to a marine vessel, the apparatus comprising:
a transom bracket configured to be supported on a transom of a marine vessel;
a swivel bracket pivotably coupled to the transom bracket; and
a steering assembly including a steering arm for an outboard motor and a steering tube extending from the steering arm;
wherein the swivel bracket includes a hollow tube in which the steering tube is seated when outboard motor is supported on the swivel bracket, and
