Abstract
A pontoon boat is provided with a jet drive propulsion system in which an impeller is driven by an engine. The jet drive propulsion device is dirigible as a result of the fact that a nozzle of the device is rotatable about a generally vertical steering axis. The jet drive device can be supported below a deck of a pontoon boat and located between two flotation tubes of the pontoon boat. Alternative locations can also be used, such as within the structure of the flotation tubes themselves.
Claims29
A marine propulsion system for a pontoon boat, comprising:
- a container;
- an internal combustion engine disposed within said container;
- and
- a jet drive device connected in torque transmitting relation with said internal combustion engine, said marine propulsion device having a dirigible segment which is supported by said container for rotation about a steering axis relative to said internal combustion engine, said container being attachable to an underside of a platform of said pontoon boat with said internal combustion engine being disposed below a top surface of said platform.
A marine propulsion system for a pontoon boat, comprising:
- a container;
- an internal combustion engine disposed within said container;
- and
- a jet drive device connected in torque transmitting relation with said internal combustion engine;
- an impeller supported for rotation by said jet drive device, said jet drive device having a dirigible segment which is supported by said container for rotation about a steering axis relative to said internal combustion engine, said internal combustion engine being accessible, from above said internal combustion engine, through a door formed in said top surface of said platform, a top surface of said platform being a flat plane in the entire region directly above said container.
A marine propulsion system for a pontoon boat, comprising:
- a container;
- an internal combustion engine disposed within said container;
- and
- a jet drive device connected in torque transmitting relation with said internal combustion engine, said marine propulsion device having a dirigible segment which is supported by said container for rotation about a steering axis relative to said internal combustion engine, said container being removably attachable to an underside of a platform of said pontoon boat with said internal combustion engine being disposed below a top surface of said platform, said internal combustion engine being disposed completely beneath an upper surface of said platform.
