Integral pedal drive for watercraft
A dual drive system for providing motive power to a watercraft has a frame configured for connecting to the watercraft and a drive assembly connected to the frame. The drive assembly has a manual drive mechanism configured for receiving mechanical input from a user, a motor drive mechanism configured for receiving mechanical input from a motor, a driveshaft having a first end in selective engagement with one of the manual drive mechanism and the motor drive mechanism and a second end in engagement with a propeller, and a drive selector for selectively engaging the manual drive mechanism or the motor drive mechanism with the driveshaft based on a position of the drive selector between first and second positions. In the first position, the drive selector engages the manual drive mechanism with a driveshaft. In the second position, the drive selector engages the motor drive mechanism with the driveshaft.
1. A watercraft comprising
a hull having a propeller;
a frame connected to the hull and movable between a fully extended position for lowering the propeller to a maximum insertion depth below the hull, and a fully retracted position for raising the propeller within the hull;
a drive assembly operatively connected to the propeller, the drive assembly having a motor drive mechanism for rotating the propeller; and
a drive selector arm movable from an engaged position, wherein the drive selector arm engages the drive assembly such that the motor drive mechanism is operatively connected to the propeller, and a disengaged position, wherein the drive selector arm disengages the drive assembly such that the motor drive mechanism is disconnected from the propeller,
wherein the motor drive mechanism has a motor with an output shaft in mechanical connection with the propeller when the drive selector arm is in the engaged position, and
wherein the motor is received within a motor housing portion, and
wherein the motor is translatable within the motor housing portion from a first position to a second position.
2. The watercraft of claim 1 , wherein the motor drive mechanism rotates the propeller by way of a driveshaft.
3. The watercraft of claim 1 , wherein the motor is in a geared engagement with a bevel gear on a driveshaft connected to the propeller such that the driveshaft rotates with rotational movement of the motor.
4. The watercraft of claim 1 , wherein the motor is an electric motor powered by a battery.
5. The watercraft of claim 4 , wherein the battery is a rechargeable battery.
6. The watercraft of claim 1 , wherein the motor has a plurality of user-selectable speed settings between a minimum rotational speed and a maximum rotational speed.
7. The watercraft of claim 1 , wherein the drive assembly has a motor housing portion for receiving the motor drive mechanism.
8. The watercraft of claim 1 , wherein the drive assembly is removably connected to the hull by one or more fasteners.
9. A watercraft comprising
a hull having a propeller;
a frame connected to the hull and movable between a fully extended position for lowering the propeller to a maximum insertion depth below the hull, and a fully retracted position for raising the propeller within the hull;
a drive assembly connected to the propeller by a driveshaft, the drive assembly having a motor with an output shaft connected to the driveshaft for rotating the propeller; and
a drive selector arm movable from an engaged position, wherein the drive selector arm engages the drive assembly such that the motor is connected to the driveshaft, and a disengaged position, wherein the drive selector arm disengages the drive assembly such that the motor is disconnected from the driveshaft,
wherein the motor is received within a motor housing portion, and
wherein the motor is translatable within the motor housing portion from a first position to a second position.
10. The watercraft of claim 9 , wherein the motor is in a geared engagement with a bevel gear on a driveshaft connected to the propeller such that the driveshaft rotates with rotational movement of the motor.
11. The watercraft of claim 9 , wherein the motor is an electric motor powered by a battery.
12. The watercraft of claim 11 , wherein the battery is a rechargeable battery.
13. The watercraft of claim 9 , wherein the motor has a plurality of user-selectable speed settings between a minimum rotational speed and a maximum rotational speed.
14. A drive assembly for providing motive power to a watercraft, the drive assembly comprising:
a motor drive mechanism having a motor for rotating the propeller; and
a drive selector arm movable from an engaged position, wherein the drive selector arm operatively connects the motor drive mechanism to the propeller, and a disengaged position, wherein the drive selector arm disengages the motor drive mechanism from the propeller,
wherein the motor is received within a motor housing portion, and
wherein the motor is translatable within the motor housing portion from a first position to a second position.
15. The drive assembly of claim 14 , wherein the motor is an electric motor powered by a rechargeable battery.
