摘要： Disclosed herein is an outboard motor mounting arrangement including first and second links pivotally connected to a bracket adapted to support an outboard motor and pivotally connected to a member adapted to be mounted on a boat hull for pivotal movement of the bracket relative to the member between a storage position and an operating position, and a tension spring which is connected between the links to releasably urge the engine support bracket towards the operating position. The links are arranged so that the support bracket moves substantially vertically during initial movement from the operating position towards the storage position to thereby reduce effort required to raise the outboard motor from the water.In one embodiment, the first link includes a rigid element which at one end is pivotally connected to the bracket and, at the other end, is pivotally connected to a support arm which in turn is pivotally mounted on the member. In another embodiment, the first link includes a rigid element which at one end is pivotally connected to the bracket and the member includes an upstanding flange having an arcuate slot in which the other end of the element is supported for pivotal and arcuate movement relative to the member.

摘要： Disclosed herein is a marine propulsion device comprising a lower unit including a gear case having a hollow interior and having at the rearward end thereof an inwardly extending inner circular surface defining an opening through which exhaust gases and engine cooling water are discharged from the lower unit, and a propeller shaft rotatably journaled in the gear case and including a portion extending rearwardly of the gear case. A propeller including a hub is mounted on the propeller shaft rearward portion for common rotation of the hub with the propeller shaft. The propeller also includes a forward portion adjacent the rearward end of the gear case, and a propeller blade extending radially outwardly from the hub. A thrust washer is carried by the propeller shaft in forward thrust transmitting engagement therewith and in forward thrust receiving engagement with the hub, and a sleeve is supported by the thrust washer and extends into an area adjacent the inner circular surface of the gear case, the sleeve having a cutting surface closely adjacent the forward portion of the propeller for cutting fish lines and weeds therebetween.
