Abstract
An internal combustion engine includes an engine block, a crankshaft configured to rotate about a crankshaft axis, a flywheel coupled to the crankshaft and positioned above the engine block, an outer housing positioned above the engine block and the flywheel, and an electric starting system. The electric starting system includes an electric motor and an energy storage device positioned above the flywheel and below the outer housing. The energy storage device is electrically coupled to the electric motor to power the electric motor. When the electric starting system is configured to rotate the crankshaft to start the engine when the electric starting system is activated.
