An outboard marine engine comprises a vertically aligned bank of piston-cylinders; a camshaft that operates a plurality of valves for controlling flow of air with respect to the vertically aligned bank of piston-cylinders, the camshaft vertically extending between a lower camshaft end and an upper camshaft end; and a cam lobe at the upper camshaft end. Rotation of the camshaft causes the cam lobe to cam open an uppermost valve in the plurality of valves. A lubricant circuit extends through the camshaft and has a lubricant outlet located at the upper camshaft end. The lubricant outlet is configured to disperse lubricant onto the uppermost valve, which is located above an uppermost cam bearing bulkhead for the upper camshaft end.
