An outboard motor 100 includes an upper case 20 arranged between an engine 1 and a propulsion unit 5. The upper case 20 is composed of a plurality of case parts 21 to 26 that are formed separately from each other and assembled together. The case parts 21 to 26 include a first case part 21 and a second case part 22 opposing each other in a direction perpendicular to an axis 7c of a drive shaft 7.

A method of controlling tilt-trim position of a trimmable device (10) on a marine vessel (30) includes receiving an engine speed, a vessel speed, a vessel pitch, and/or a vessel acceleration. A trim rate is then determined based on the engine speed, the vessel speed, the vessel pitch, and/or the vessel acceleration. The trim rate specifies a rate of rotation of the trimmable device (10) about a horizontal axis (26), and the trim rate is determined such that the rate of rotation is minimized at high vessel speeds and high engine speeds and the rate of rotation is maximized at low vessel speeds and low engine speeds. A variable speed trim actuator (28) is then controlled to rotate the trimmable device (10) based on the trim rate so as to adjust a trim position of the trimmable device (10).

An inner circumferential surface of a clamp bracket is open at an inner side surface of the clamp bracket. At least a portion of a movable body is surrounded by the inner circumferential surface in a side view. The movable body is movable to a plurality of positions including a position above a swivel bracket and a position inside a space surrounded by the inner circumferential surface of the clamp bracket. A steering shaft rotates around a steering axis along with movement of the movable body.

Disclosed are a canister type thruster for implementing smooth upward/downward movement and improving productivity and an installation method thereof. The canister type thruster includes a guide module for guiding upward/downward movement of a canister. The guide module includes: a guide unit that is installed on an inner surface of a trunk so as to support a rack installed on an outer surface of the canister in parallel with a lifting direction to guide the upward/downward movement of the canister; a sliding pad that relieves an impact or a friction applied to the guide unit; and a support protrusion that is provided between the guide unit and the sliding pad to support the sliding pad.

The outboard motor control system comprises a plurality of outboard motors, a vibration detecting section, and a control section. The outboard motors are mounted on a stern of a watercraft. Each of the outboard motors includes a propeller. The outboard motors are configured to be steered independently of one another. The vibration detecting section is configured to detect a vibration of the outboard motors. The control section is configured to execute a vibration suppressing control when the vibration detecting section detects a vibration of the outboard motors. With the vibration suppressing control, the control section is configured to change a propeller rotational axis direction and/or a propeller position of at least one of the outboard motors.

A vessel, including a transom for mounting outboard engines thereto, is spanned on opposite sides by aft-facing hull extensions which extend beyond the engines and allow a swim platform to be positioned between the hull extensions. The design allows the outboard engines to be covered with an engine cover, which provides an attractive vessel design in which the outboard engines can be concealed with a cover, which may serve other functions, such as a seat or the like. The cover houses an engine cowl mist shield which includes a support frame surrounding one or more outboard engines. The frame includes aperture(s) with edges spaced from the cowl and a flexible member extending from the edges to the cowl below the air intake of the cowl, such that spray and mist from the operation of the vessel does not reach the air intake of the cowl.
摘要:
A marine articulated surface drive propulsion system is provided with a housing construction that allows the direct application of an electric motor for power onto the drive structure. Alternatively, it can include a power transmitting element for reducing the rate of rotation or the position of the motor shaft with respect to the propeller shaft. The drive can be retrofitted to existing boat hulls and does not require a dedicated hull. The electric motor can be fitted to the surface drive housing on the inside of the transom. It is contemplated that an electric motor with very small dimensions can be mounted in the drive thrust tube and ball socket, eliminating the need for U joints. Notably, if the propeller is left free wheeling it becomes the propulser for the electric motor to become a generator and recharge the batteries.
