Abstract: A boat propelled by a motorcycle. The boat propelled by a motorcycle has a portable ramp to get the motorcycle on and off. The motorcycle produces rotational energy by its driven wheel and transmits it to a pair of rollers covered by rubber or any nonslippery material. The motorcycle is fastened to the boat by two yokes which support the pedals making them like one piece without movement, except if the whole boat gets moved. Fore roller transmits the driving force to a gear which has a sprocket chain mounted and at the other end of this, has another gear which makes an axis spin that is connected to a gear box. Another shaft extends out of the gear box and makes the propeller spin to move the boat. The gear box has forward propeller direction and reverse propeller direction. The aft roller makes two pulleys spin which make two transmission bands spin and make two more pulleys spin which make two ducted fans spin, one on each side of the engine of the motorcycle and cool it off.
