  • Separate lubricating system for outboard motors
    Patent number: 4637355
    Abstract: A lubricating system for a two-cycle outboard motor in which lubricant is mixed with the fuel prior to delivery to the fuel bowl of the carburetor in a chamber located externally of the carburetor. The lubricant is supplied by a relatively large storage tank to a relatively smaller delivery tank that is positioned in proximity to the engine. A float operated control device is provided for maintaining an adequate lubricant level in the delivery tank and an arrangement is incorporated for insuring against operation of the pump in response to momentary changes in liquid level in the delivery tank due to inertial effects.
    Type: Grant
