Abstract
A lubricating system for a two cycle engine, particularly of the outboard type, wherein the engine has a separate lubricating system and lubricant is supplied to this system by a relatively small delivery tank via gravity feed. In addition, an arrangement is provided for supplying lubricant to the delivery tank from a separate oil storage tank to maintain a predetermined liquid level in the delivery tank. This system includes a pump located in the separate storage tank. In accordance with certain embodiments of the invention, the pump is operated if the liquid level in the delivery tank falls below a predetermined level. In accordance with one embodiment, the operation of the pump is stopped when the liquid level exceeds a predetermined level.
