Definitions

• the present Invention of the Overboard Drive Mechanism relates to propulsion and maneuverability of boats on water.
• the present invention of the Overboard Drive Mechanism is not known to me in the prior art.
• the only cycling boat known to me that transmit motion from the power wheel via a gearbox to the propeller is the Hydropedalptane patent Number UM 43.
• the Hydropedalplane has motion transmission system below the floor of the boat and the propeller also operates under the boat.
• the system has three main technical problems. Due to its keel drop, it is not easy to load the boat on the trailer and offload at sea for operation. You have to use other lifting mechanism for loading and offloading, which is expensive and cumbersome. Secondly it is not easy to carry out repairs while the boat is floating on water. Third the boat has always to lie on its side when stationary due to the keel drop. This makes the sand to scratch the paint and deface the sides of the hull, which increase the maintenance costs.
• the known prior art cannot also propel the boat with more than eight people with one operator or cyclist (Manual operation). Double cycling or pedaling of the prior art has been designed for uniform pedaling or cycling and the system is not designed for individual cycling with different speeds while rotating a single propeller.
• Motorized boats of prior art do not use Air for propulsion and do not use air cooled engine. Their propulsion mechanism is not convertible for Air and Water, and the boat cannot reverse without engaging reverse gear.
• Prior art do not have a system that can be coupled to manual power, solar or air cooled engine.
• the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of effectively propelling boats on water by use of Overboard drive mechanism.

It is further object of the present invention to provide new Overboard Drive Mechanism which is, durable and reliable construction. An even further objective of the present invention is to provide new Overboard Drive Mechanism, which is susceptible of low cost manufacturing with regard to both materials and labor, and which accordingly is then susceptible to low prices of sale to consuming public, thereby making such Overboard Drive Mechanism economically to buying public.
• Another object of the present invention is to provide a new Overboard Drive Mechanism which can make it possible to develop future boats that can be used for water sport such as High Speed racing boats by manual powering and to be able to attract National, Regional and Internationa! water sport.
• Still yet another object of the present invention is to provide new Overboard Drive Mechanism, which is portable and easy to transport, install and even repair while the boat is floating on the water and that you can use the same mechanism to maneuver the boat.
• Even still another object of the present invention is to transmit motion from cycling means, solar system and air cooled engine to propeller and propel the boat on water. Also another object of the present invention is for the use of Navy Officers ail over the world for physical fitness and to get rid of fear factor by regular riding on water. Another object of the present invention is to reduce carbon emission in the Air and noise, thus making the water craft environmental friendly.
