Abstract: A marine engine has a crankcase and a cylinder bank. An upper end of the cylinder bank defines a plane. A cylinder head is connected to the upper end of the cylinder bank. A crankshaft is disposed in the crankcase. A pump is operatively connected to the crankshaft so as to be operatively driven thereby. A center of the pump is disposed above the plane defined by the upper end of the cylinder bank. In another aspect, a marine engine has a crankcase and a crankshaft. A starter ring gear is disposed on an end portion of the crankshaft. A diameter of the starter ring gear is less than a width of the crankcase. A starter motor selectively engages the starter ring gear and is disposed such that the starter ring gear is disposed between the crankcase and the starter motor.

Abstract: A two-stroke internal combustion engine has two cylinders each having an exhaust port. Two exhaust conduits are connected to the two exhaust ports. A passage is provided between the two conduits to fluidly communicate the two together. An actuator moves a valve to open or close the passage depending on the engine speed.
