Appeal No. 96-2248
Application 08/341,455
1 through 12 and 14 through 16. These are the only claims
remaining in the application.
The claimed invention is directed to a small watercraft
of the inboard, jet-propelled type. The invention comprises
mounting the entire jet propulsion unit relative to the hull
by
a plurality of resilient supports 80 as to ensure against the
transmission of vibrations from the jet propulsion unit to the
hull. Claim 1, reproduced below, is further illustrative of
the claimed subject matter.
1. A small watercraft having a hull with a tunnel formed
in the underside thereof, an engine having an engine output
shaft mounted in said hull, a jet propulsion unit comprising
an outer housing defining a water inlet passage extending from
a water inlet opening surrounded by a flange positioned in
juxtaposition at least in part to said hull, an impeller unit
containing an impeller and a discharge nozzle, said engine
output shaft coupled, via an elastic vibration dampening
connection, to an input end of a power transmitting shaft
system, for supplying power to said impeller, and a plurality
of vibration insulating connector assemblies serving the sole
function of mounting said outer housing to said hull within
said tunnel including a vibration damper interposed between
said outer housing flange
and said juxtaposed portion of said hull for precluding any
direct contact there between.
The references of record relied upon as evidence of
obviousness are:
