Abstract:
A watercraft propulsion device for protecting marine life includes a tube that is coupled to a hull of a marine vessel. The tube has a front end and a back end that are open. The front end is circumferentially larger than the back end so that the tube is tapered. An impeller assembly is positioned in the tube. The impeller assembly is operationally coupled to a drive shaft of the marine vessel. A power plant of the marine vessel is positioned to rotate the impeller assembly concurrently with the drive shaft to increase a pressure and a flow of water through the tube to generate thrust to propel the marine vessel. A grate is coupled to a front perimeter of the tube so that the grate covers the front end. The grate is configured to deter entry of a marine organism into the tube.

Claim (Index 13):
A watercraft propulsion device comprising:\n a tube coupled to a hull of a marine vessel, the tube having a front end and a back end, the front end and the back end being open, the front end being circumferentially larger than the back end such that the tube is tapered; an impeller assembly positioned in the tube, the impeller assembly being operationally coupled to a drive shaft of the marine vessel wherein a power plant of the marine vessel is positioned for rotating the impeller assembly concurrently with the drive shaft for increasing a pressure and a flow of water through the tube for generating thrust for propelling the marine vessel; a grate coupled to a front perimeter of the tube such that the grate covers the front end wherein the grate is configured for deterring entry of a marine organism into the tube; a baffle coupled to and positioned in the tube proximate to the back end wherein the baffle is configured for selectively controlling the flow of the water through the back end of the tube for adjusting a speed and a direction of the marine vessel; a plate, the plate being semi-circularly shaped defining a straight edge and a curved edge of the plate, the plate being coupled to and extending between the back perimeter of the tube; and a baffle actuator coupled to the tube, the baffle actuator being linear-type, the baffle actuator being operationally coupled to the plate wherein the baffle actuator is positioned for selectively urging the plate from an open configuration wherein the plate is substantially perpendicular to the back end to a closed configuration wherein the curved edge of the plate abuts the tube.
