The present disclosure relates to a houseboat assembly formed from a cabin assembly secured to a hull assembly. In some version of the houseboat assembly, the hull assembly may include a runoff flange. The runoff flange may include an inner flange, an outer flange, and a riser extending between the inner flange and the outer flange. The outer flange may extend along an imaginary longitudinal outer flange axis and the riser may extend along an imaginary longitudinal riser axis whereby the riser axis intersects the outer flange axis at an angle. In some versions of the houseboat assembly, the angle is an acute angle. More specifically, the angle may be between thirty and sixty degrees. In some versions of the houseboat assembly, the cabin assembly is secured to the inner flange of the runoff flange. Cross-members and deck boards may be secured to a roof of the cabin assembly.

A sailing assisting system is provided in which a sailing assist for a vessel which enters a specific water area where sailing of the vessel is limited is realized through a simple configuration and in which a steersman is prevented from having strange feeling. A sailing assisting system includes movable controlling devices (a shift and throttle controller, a steering device, a trim switch), actuators (a rotational shaft drive unit, a shaft drive unit, a switch drive unit) for driving these controlling devices, and a control unit for executing a notification operation and controlling the actuators to limit movable ranges of the controlling devices if a hull is determined to stay within a specific water area where the sailing of the hull is limited based on information on the specific water area and information on the position of the hull.

A marine propulsion system for a marine vessel has an outboard motor including a cowl covering an internal combustion engine that powers the outboard motor and an accelerometer mounted to the outboard motor. A control module is communicatively connected to the accelerometer. The control module receives information regarding an acceleration of the outboard motor from the accelerometer. The control module uses the information regarding the acceleration of the outboard motor to do at least one of the following: determine an angle of the outboard motor with respect to gravity; determine an amount of oil in an oil sump of the outboard motor; and determine if a reading of the amount of oil in the oil sump is accurate.

A watercraft and a marine engine assembly for mounting to a watercraft are disclosed. The marine engine assembly includes an engine unit including: an engine unit housing being sealed such that water in which the engine unit housing is immersed is impeded from entering the engine unit housing; an engine in the housing; and an air intake assembly in the engine unit housing which forms a conduit between an exterior of the engine unit housing and the engine, the air intake assembly defining an inlet fluidly communicating with exterior air, the engine unit housing defining at least one aperture aligned with the inlet, the air intake assembly defining at least one outlet fluidly connected with the engine intake, the air intake assembly being sealed such that surrounding fluids within the engine unit housing are impeded from entering the air intake assembly; and a propulsion device operatively connected to the engine.

A shift mechanism configuring an outboard motor comprises: an electric actuator that linearly moves a movable rod; and a shift shaft portion that switches from neutral to forward or reverse based on displacement of said movable rod. Moreover, a neutral adjusting mechanism enabling a neutral position of the shift mechanism to be adjusted is provided facing the shift shaft portion, by a separate body. The neutral adjusting mechanism, which comprises first and second adjusting arms that are supported in a freely rotating manner with respect to a frame and that have been biased in contrary directions to each other by elastic springing force of a coil spring, is provided in a manner that an adjusting screw mounted in the first adjusting arm capable of abutting on a shift arm always abuts on a contacting wall of the second adjusting arm capable of contacting a switch sensor.

A marine propulsion system for a marine vessel has a first marine propulsion device coupled to the marine vessel and a second marine propulsion device coupled to the marine vessel. The first marine propulsion device has a first engine controlled by a first electronic control module. The second marine propulsion device has a second engine controlled by a second electronic control module. In response to the first marine propulsion device being keyed ON, the second electronic control module of the second marine propulsion device is turned ON.
