Abstract
An engine has a valve drive arrangement that uses dead space within an outboard motor cowling. The engine has a first set of cylinders and a second set of cylinders. The first set of cylinders is offset from the second set of cylinders such that one is arranged closer to a first end of the engine that the other. The higher set of cylinders includes a set of cam shafts that are coupled at the end closer to the first end of the engine while the lower set of cylinders includes a set of cam shafts that are coupled at the end farther from the first end of the engine. A drive arrangement connects the two sets of cam shafts to the crankshaft.
