A medical line securement device holds a medical article such as a connector fitting for a catheter or a catheter adaptor in position upon the body of a patient and inhibits axial motion of the medical article. The securement device includes a retainer with a base and a cover. The cover is hinged to the base such that it may be moved between an open and closed position. The base and cover each have a groove which cooperate when the cover is in the closed position to form a channel through the retainer. The medical article includes an elongated body which is received within the groove of the retainer, the elongated body lying between at least a pair of regions of larger radius of the medical article. By receiving the portion of the elongated body of the medical article between the regions of larger radius, axial motion of the medical article through the groove is inhibited. The retainer may also include one or more slots to receive any radial projections of the medical article within the retainer.

In an outboard motor steering system for an outboard motor mounted on a stern of a boat and having an internal combustion engine at its upper portion and a propeller with a rudder at its lower portion powered by the engine to propel and steer the boat, a controller is connected to an actuator to rotate the outboard motor relative to the boat, and controls the actuator in such a manner that steered angle of the outboard motor relative to a steering angle inputted through a steering wheel becomes a predetermined ratio that is changed such that the steered angle of the outboard motor relative to the steering angle decreases with increasing moving speed of the boat. Alternatively, a switch is provided to be manipulated by the operator and generating a signal indicative of an instruction to change the steered angle of the outboard motor when manipulated; and the controller controlling the actuator to steer the outboard motor to an angle in response to inputted steering angle when the switch is not manipulated, while controlling the actuator to change the steered angle when the switch is manipulated. With this, the burdens of the operator are lightened and the steering feel is improved, in particular when the operator steers the boat to approach or leave a quay.

A system for optimizing the operation of a marine drive of the type whose position may be varied with respect to the boat by the operation of separate lift and trim/tilt means includes an automatic control system which stores preselected drive unit positions for various operating modes and is operative to return the drive unit to any pre-established position by pressing a selected operating mode positioning button. The various operating modes may include cruising, acceleration, trolling and trailering position, any of which may be selectively modified to accomodate changes in both operating or environmental conditions. This system may incorporate other optimization routines and/or automatic engine protection systems to provide virtually complete push button operation for complex marine drive unit positioning mechanisms.

The marine propulsion device includes a propulsion unit mounted for tilting movement about a generally horizontal tilt axis and for pivotal steering movement about a vertical steering axis, and a power steering system adapted to operably connect an actuator to the propulsion for increasing the steering force applied to the propulsion unit by the actuator. The power steering system is wholly supported on the propulsion unit and includes a hydraulic cylinder-piston assembly having an axis extending in fixed parallel rotation to the tilt axis and including a cylinder, a piston mounted in the cylinder, and an extendable and retractable piston rod connected to the piston, and a control valve connected to a source of pressurized hydraulic fluid for selectively controlling the flow of hydraulic fluid to and from the opposite sides of the piston to extend and retract the piston rod. The control valve includes a valve member and valve housing rotatably and axially movable relative to each other. The valve member is connected to the actuator and the valve housing is connected to the piston rod for common movement and is connected to the propulsion unit to affect steering movement thereof in response to movement of the actuator.

In one embodiment of the present invention an apparatus (30) for controlling one or more engines (32) by synchronizing the functions of two or more electronic control modules (70, 72, 74) includes a master electronic control module (70), one or more slave electronic control modules (72, 74), and one or more data links (76, 106) for transferring data between the electronic control modules (70, 72, 74). Engine control and monitoring functions are divided between the master electronic control module (70) and the slave electronic control modules (72, 74). The present invention may be used to control and monitor dual fuel engines (32) and engines that operate on one type of fuel. The master electronic control module (70) may transition operation of the engine (32) to the diesel fuel only mode in the event of a failure of any dual fuel mode specific components. The master ECM (70) coordinates timing and speed of fuel injection to engine cylinders (34, 35) using input from an adjustable engine speed command device and a speed sensor connected to each engine (32). The loads driven by the engines (32) may be allocated evenly or unevenly.
