applied prior art. Therefore, all rejections on appeal are
affirmed. Our reasons follow.
The following represents our findings of fact with
respect to the rejections on appeal:
The Japanese reference to Kuroi discloses a hydraulic steering
assembly for an outboard propulsion watercraft which can
rotate two propulsion units 1 about their vertical axes in
unison to steer the craft. The outboard propulsion units can
be tilted up out of the water as shown in Figure 1a.
Translation (here-inafter Tr.) at 15. This tilting motion is
provided by tilt tube 15. Tr. at 15. The tiller 17
provides a means to steer by
swinging the propulsion units from side to side. Tr. at 15.
This side to side motion is accomplished by piston cylinder
20, 21 which is mounted coaxial with the tilt tube. Tr. at
16. The hydraulic steering linkage the examiner relies on is
shown in Figures 5, 11 and 12. In Fig. 5, the output of the
piston cylinder is pivotally connected to member 31, which is
connected to tiller 17 of a first propulsion unit through the
