fig4 swing arm 37 is rotated by cylinder 41 fig2 causing said retraction of suspension and therefore wheels as swing arm 37 rotates the proximal end of cable 35 is pulled the distal end of cable 35 therefore rotates wheel 33 which in turn rotates arbor 31 and thus connection 27 in direction r in fig6 until connection 27 is substantially vertical to effect wheel protraction cylinder 41 extends and swing arm 37 rotates in the opposite sense to that for protraction cable 35 is then pushed causing wheel 33 to rotate in direction p in fig7 until connection 27 is substantially horizontal as shown in fig6 alternatively the wheel 33 could be spring biased and rotated against the spring bias by the cable in tension and then rotates under the bias of the spring in the opposite directions as the distal end of connection 27 now lies at a radius from axis x it is once more able to steer the vehicle through link 25 and track rod 23 marine steering will still be engaged in this land mode however as no water is passing through the jet drive on land it will have no effect other than to swing the steering bucket from side to side.
