Abstract
A lubricating system for a two cycle internal combustion engine as applied to an outboard motor wherein small amounts of lubricant can be pumped by a diaphragm type pump through the use of an air bleed that mixes air with the lubricant being pumped. Pulsation variations are minimized by supplying the pump with lubricant with a constant volume delivery chamber.
