摘要： A position control system for a marine propulsion device senses an undesirable operating condition in the propulsion engine, such as low cooling water pressure at high speed or high engine temperature, to automatically lower the drive unit to a position in which the undesirable operating condition is likely to be alleviated. The system may include a logic timer circuit which will lower the drive unit for a short period of time, hold it in that position if the undesirable condition has been eliminated, or lower the drive unit further if the undesirable operating condition remains. The position control system may be incorporated into a conventional lift system, particularly a lift system used with a transom extension mounting assembly.

摘要： In a two cycle internal combustion engine (2), a turbulence generator (70) is provided by a freely rotating fan (72) in the fuel-air stream to the reed valves (16) which supply the fuel-air mixture into the crankcase chamber (8). The freely rotating fan (72) is driven by the fuel-air mixture flow and rotates to generate turbulence to provide more uniform distribution of the fuel-air mixture.

摘要： A mounting assembly for an outboard motor includes a motor mount having a transom mounting bracket attachable to a boat transom and a motor supporting bracket spaced aft of and pivotally connected by upper and lower links with the transom mounting bracket to support an outboard motor wholly aft of the boat transom, and cylinder means for moving the motor supporting bracket relative to the transom mounting bracket to simultaneously move the outboard motor between raised and lowered positions in a vertical plane which extends parallel to the longitudinal dimension of a boat and to rotate the motor about a horizontal axis which extends perpendicular to the vertical plane. The movement of the outboard motor is provided by the motor mount being a quadrilateral structure wherein the lower link is shorter in length than the upper link and the motor supporting bracket is shorter in length than the transom mounting bracket.

摘要： A marine drive has a reverse thrust cup on the propeller shaft between the propeller hub and the rear retaining nut. The reverse thrust cup permits the propeller hub to slide on the propeller shaft fore and aft. When the marine drive is in the forward direction the rearward thrust of the propeller forces the propeller hub to the forward position thereby directing engine exhaust out the rear of the propeller hub. Conversely, when the marine drive is in the reverse direction, the forward thrust created by the propeller hub forces the propeller hub to the rearward position thereby directing exhaust out a forward exhaust opening forward of the propeller blades increasing the reverse thrust of the marine drive.
摘要翻译：船用驱动器在螺旋桨毂和后固定螺母之间的传动轴上具有反向推力杯。反向推力杯允许螺旋桨轮毂在前后驱动轴上滑动。当船舶驱动器处于向前的方向时，推进器的向后推力迫使螺旋桨轮毂到达前进位置，从而将发动机排气引导到螺旋桨轮毂的后部。相反，当船舶驱动器处于相反方向时，由推进器轮毂产生的向前推力迫使推进器轮毂到达后部位置，从而引导排出向前的螺旋桨叶片前排气开口，从而增加船舶驱动器的反向推力。

摘要： An actuator of a marine propulsion transmission is attached to a movable clutch member through the use of a coupler which comprises a generally spherical member formed as a portion of the actuator and a chuck device formed as part of the clutch member. The generally spherical member, or alternatively shaped component, is received by the chuck device and retained therein. The components are configured to allow relative rotation between the actuator and the clutch member while causing them to move axially in synchrony with each other.

摘要： A pontoon boat is provided with a jet drive propulsion system in which an impeller is driven by an engine. The jet drive propulsion device is dirigible as a result of the fact that a nozzle of the device is rotatable about a generally vertical steering axis. The jet drive device can be supported below a deck of a pontoon boat and located between two flotation tubes of the pontoon boat. Alternative locations can also be used, such as within the structure of the flotation tubes themselves.

摘要： An electrically powered automatic choke system for a turnkey outboard motor has a thermostatic override switch. The automatic choke feature is often not necessary, and sometimes not even desirable, when restarting the engine. The thermostatic override switch prevents the automatic choke from closing carburetor choke shutters when the ambient temperature near the engine under the cowl exceeds a choke deactivation temperature. A switch assembly is provided to retrofit engines on existing outboard motors.

摘要： A system for optimizing the operating efficiency of a boat by balancing fuel consumption against cruising speed utilizes a comparison between engine speed and boat speed to effect automatic positioning of the drive unit. The measurements of boat and engine speed before and after an incremental change in vertical position or trim position are used to calculate the percent changes in boat speed and engine speed which, in turn, are used in conjunction with selected minimum and maximum incremental percentages to effect subsequent alternate control strategies. Depending upon the relative difference in the percent changes in boat and engine speeds, including adjustments based on the minimum and maximum incremental percents, the system will automatically continue incremental movement of the drive unit in the same direction, hold the drive unit in its present position, or move the drive unit an incremental amount in the opposite direction. Operating efficiency is optimized by eliminating incremental drive unit movement which results in an engine speed increase and consequent increase in fuel consumption which is disproportionate in the increase in boat speed attained.
摘要翻译：用于通过平衡燃料消耗与巡航速度来优化船的操作效率的系统利用发动机转速和船速之间的比较来实现驱动单元的自动定位。使用垂直位置或修剪位置增量变化前后的船舶和发动机转速的测量值来计算船速和发动机转速的百分比变化，而转速和发动机转速又与选定的最小和最大增量百分比结合使用随后的替代控制策略。根据船舶和发动机转速百分比的相对差异，包括基于最小和最大增量百分比的调整，系统将自动继续沿同一方向驱动单元的增量运动，将驱动单元保持在当前位置，或者以相反的方向移动驱动单元的增量。通过消除增量驱动单元运动来优化运行效率，从而导致发动机转速增加，从而增加燃料消耗，这在所获得的船速提高方面是不成比例的。

摘要： A tell-tale system is provided for an outboard motor in which the tell-tale fluid conduit is connectable to an external water source, such as a water hose, and is extendable away from the cowl of the outboard motor in order to facilitate its use during a flushing operation. When not being used in the flushing procedure, the connector of the fluid conduit is snapped into position in connection with the cowl to maintain its position when used as a tell-tale port.
