Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to boat drag reduction systems and more particularly pertains to a new boat propulsion system for propelling a boat through water with debris in the water and shallows.




2. Description of the Prior Art




The use of boat drag reduction systems is known in the prior art. U.S. Pat. No. 4,592,299 describes a system for providing a rudder that produces less drag when the vessel is traveling through the water. Another type of boat drag reduction system is U.S. Pat. No. 4,925,412 having a weed deflector that deflects weeds away from the propeller of an outboard motor to prevent the weeds from fowling the propeller of the motor. U.S. Pat. No. 4,553,945 has a safety shroud that is positioned over a propulsion system for a boat to inhibit inadvertent access to the propeller and thereby inhibiting injury due to contact with propeller. U.S. Pat. No. 4,337,053 has a throttle control grip that is coupled to the marine propulsion unit and is sculpted to provide greater comfort to a user when the user is operating the marine propulsion unit. U.S. Pat. No. 3,698,497 has a variable speed transmission system coupled to a motor for a snowmobile to provide power to drive the endless track of the snowmobile. U.S. Pat. No. 1,730,844 has a detachable fin for boats to allow for transportation of the boat with out damaging the fin. U.S. Pat. No. 2,956,533 has a rudder attachment that is coupled to outboard motors to allow the user to steer the boat when the propeller is not rotating or is rotating at an extremely slow speed. U.S. Pat. No. 6,276,230 has a throttle control that is positioned at the end of handle bar to allow the user to control the operating speed of a motor when the hand of the user is positioned on the handle bar. U.S. Pat. No. 4,241,687 has a throttle control that is operationally coupled to an outboard motor that allows the user to control the speed of the outboard motor by twisting the throttle control. U.S. Pat. No. 5,249,993 has a boat propeller that is resistant to becoming fowled by weeds. U.S. Pat. No. 4,911,663 has a system for reducing weed migration between the gearcase and the propeller hub when a small hub propeller is used. U.S. Pat. No. 4,954,108 has a line cutter that is positioned adjacent a propeller of an outboard motor to cut fishing lines, weeds and such away from the propeller to inhibit the items from fowling the propeller.




While these devices fulfill their respective, particular objectives and requirements, the need remains for a system that has certain improved features that allows a boat to operate in the shallows of a body of water without being impeded by mud and objects positioned in the water.




SUMMARY OF THE INVENTION




The present invention meets the needs presented above by providing a deflector member that extends away from the sleeve member and deflects objects in the water away from the propeller as well as cutting into the mud to loosen the mud and allow the propeller member to rotate through the mud and continue propelling the boat through the water.




Still yet another object of the present invention is to provide a new boat propulsion system that provides a sleeve member positioned around the drive shaft


18


to protect the drive shaft


18


from being damaged by objects in water that might gouge the drive shaft


18


and cause the drive shaft


18


to become unbalanced.




Even still another object of the present invention is to provide a new boat propulsion system that provides a torque converter to allow power to be transferred to the propeller member to allow the propeller member to power through thicker substances and continue propelling the boat through the water.




To this end, the present invention generally comprises a motor assembly being designed for being positioned in a boat. A propeller member is operationally coupled to the motor assembly whereby the propeller member is rotated by the motor assembly. The propeller member is designed for being positioned under the boat whereby the propeller member is positioned in the water for rotating in the water to propel the boat through the water when the propeller member is rotated by the motor assembly. A direction assembly is designed for being coupled to the boat. The direction assembly is designed for being actuated by the user whereby the direction assembly is for controlling the direction of the boat when the propeller member is propelling the boat through the water.




There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.

16


and uses the throttle assembly to control the speed of the boat. The control arm


36


is pivoted one direction to pivot the rudder member


34


one direction to steer the boat in a first direct with the control being pivoted in a second direction to pivot the rudder member


34


in a second direction to steer the boat in a second direction. The deflector member


31


allows the boat to be used in shallow areas by deflecting objects in the water away from the propeller member


12


and cutting into the mud so that propeller member


12


can continue to propel the boat through the water.

at least one deflector member being coupled to said sleeve member, said deflector member extending outwardly from said sleeve member such that said deflector member is adapted for extending away from the boat, said deflector member being adapted for deflecting objects in the water away from said propeller member to inhibit the objects from fowling said propeller member; said deflector member comprising a terminal edge, said terminal edge of said deflector member being positioned opposite said sleeve member, said terminal edge of said deflector member extending below said propeller member such that said terminal edge of said deflector member forces objects in the water below said propeller member to inhibit the objects from fowling said propeller member; said deflector member comprising a plate, said plate being aligned with a longitudinal axis of said sleeve member, said plate being adapted for extending along a portion of the length of the boat such that said plate creates minimal drag through the water when the boat is being propelled through the water, said plate being adapted for slicing into mud under the water and forcing the mud away from the propeller member; said propeller member comprising a pair of blades, one of said blades being positioned diametrically from the other one of said blades such that said blades are adapted for rotating in the water in a screw type movement to propel the boat through the water when said propeller member is being rotated; said direction assembly comprising a rudder member, said rudder member comprising a pair of deflecting faces, said rudder member being adapted for being pivotally coupled to the boat such that said rudder member is positioned behind said propeller member, said rubber member being adapted for being rotated by the user such that said rudder member is deflecting water passing under the boat off of one of said deflecting faces to turn the boat a desired direction; said direction assembly comprising a control arm, said control arm adapted for being pivotally coupled to the boat such that said control arm is positioned proximate the user in the boat, said control arm being operationally coupled to said rudder member such that said control rudder member is pivoted with respect to the boat when the user pivots said control arm with respect to the boat; said direction assembly comprising a linkage assembly, said linkage assembly being operationally coupled between said control arm and said rudder member, said linkage assembly translating pivotal movement of said control to pivotal movement of said rudder member when said control arm is pivoted with respect to the boat by the user; and a throttle control assembly being coupled to said control arm of said direction assembly such that said throttle control assembly is adapted for being actuated by the user when the user is.using said control arm to control the direction of the boat, said throttle control assembly being operationally coupled to said motor assembly such that said throttle control assembly is for controlling the motor assembly to control the rate at which said motor assembly rotates said propeller member when said throttle control assembly is actuated by the user.
