An outboard marine engine comprises a vertically aligned bank of piston-cylinders; an intake camshaft that operates a plurality of intake valves for controlling inflow of air to the bank of piston-cylinders; an exhaust camshaft that operates a plurality of exhaust valves for controlling outflow of exhaust as from the bank of piston-cylinders; and a cam-to-cam connector that connects the intake camshaft to the exhaust camshaft such that rotation of one of the intake and exhaust camshafts causes rotation of the other of the intake and exhaust camshafts. The cam-to-cam connector is located vertically above a lowermost intake valve in the plurality of intake valves, vertically above a lowermost exhaust valve in the plurality of exhaust valves, vertically below an uppermost intake valve in the plurality of intake valves and vertically below an uppermost exhaust valve in the plurality of exhaust valves.
