Abstract
An outboard marine engine comprises a vertically-aligned bank of piston-cylinders. An axially elongated camshaft operates a plurality of valves for controlling flow of air with respect to the vertically-aligned bank of piston-cylinders. The camshaft vertically extends between a lower camshaft end and an upper camshaft end. A lubricant passage axially conveys lubricant through the camshaft. An air outlet is located at the upper camshaft end. A valve is configured to open and close the air outlet to thereby facilitate lubrication of the plurality of valves at startup of the outboard marine engine.
