ABSTRACT:
Several embodiments of separate lubricating systems for two-cycle internal combustion engines and particularly those of outboard motors. In each embodiment, the lubricating system includes a relatively large lubricant storage tank that is adapted to be carried in the hull of the associated watercraft and a relatively small lubricant delivery tank carried by the engine of the outboard motor. A pump is provided for transferring lubricant from the storage tank to the delivery tank and warning devices are incorporated to indicate when the level in each of the tanks falls below a predetermined value. Furthermore, the transfer pump is disabled upon the falling of the level of the liquid in the storage tank below a predetermined value. The pump is positioned in proximity to this storage tank and is juxtaposed and plumbed in such a way that it will not pick up foreign particles from the bottom of the tank, but will always have its inlet and outlet subject to liquid so that the pump will not run dry. A system is provided for disabling the pump if the motor is tilted up and the delivery tank is vented in such a way that lubricant will not be spilled when the engine is tilted up and regardless of its angular position. Several embodiments of arrangements are disclosed for delivering lubricant from the delivery tank to the various components of the engine.
