The marine vessel according to claim 2, further comprising: a ceiling portion that is disposed above the outboard motor locating hole and covers the outboard motor. 8. The marine vessel according to claim 2, wherein the platform includes an upper portion arranged in a stepped manner that is higher in a forward direction thereof. 9. The marine vessel according to claim 4, further comprising: a hatch that closes the notched hole; anda joint member that joins the hatch to the platform in such a manner that the hatch is openable. 10. The marine vessel according to claim 9, wherein the hatch is arranged such that at least a portion of an upper surface of the hatch is flush with an upper surface of the platform in a state in which the hatch is closed. 11. The marine vessel according to claim 9, further comprising: a tilt detection mechanism that detects a tilting state of the outboard motor;an opening/closing sensor that detects opening/closing of the hatch; anda control device that receives detection values of the tilt detection mechanism and the opening/closing sensor and controls the outboard motor based on the detection values; whereinthe control device is programmed to stop turning of the outboard motor when the lower portion of the outboard motor reaches a position adjacent to the notched hole in a state in which the hatch is not opened and the lower portion of the outboard motor is moved upward by turning the outboard motor. 12. The marine vessel according to claim 9, further comprising: a tilt detection mechanism that detects a tilting state of the outboard motor;an opening/closing sensor that detects opening/closing of the hatch;an opening mechanism that includes an opening actuator arranged to open the hatch and that moves the hatch in a direction in which the hatch opens; anda control device that receives detection values of the tilt detection mechanism and the opening/closing sensor and controls the outboard motor and the opening actuator based on the detection values; whereinthe control device is programmed to: detect whether the hatch is opened or closed before the lower portion of the outboard motor passes through the notched hole based on detection values of the tilt detection mechanism and the opening/closing sensor when the outboard motor is turned until the lower portion of the outboard motor moves to a position above the platform;open the hatch before the lower portion of the outboard motor passes through the notched hole by controlling the opening actuator when the hatch is not opened; andcause the lower portion of the outboard motor to pass through the notched hole in a state in which the hatch is opened. 13.
