Abstract
An electrical system is disclosed for a watercraft powered by an outboard motor with an internal combustion engine having a block defining a crankcase at one side and having a cylinder head generally positioned on an opposite side thereof, the engine oriented such that an output shaft thereof extends vertically. The electrical system includes a starter and generator mounted generally alongside the crankcase of the engine and between the ends thereof, the generator driven by a flexible belt extending in engagement with the output shaft, and the starter motor positioned for engagement with a flywheel positioned on the output shaft of the engine.
Claims7
A watercraft powered by an outboard motor having an internal combustion engine powering a water propulsion device, said engine mounted within a cowling of said motor and having a block defining a crankcase at one side and having a head mounted thereto on another side and cooperating therewith to define at least one variable volume combustion chamber, said engine having an output shaft extending generally vertically such that a first end thereof extends beyond a top end of said engine and a second end thereof extends beyond a bottom end of said engine for driving said water propulsion device, a drive pulley positioned on said first end of said output shaft, at least one camshaft generally vertically extending and driven by said output shaft by a camshaft drive mechanism positioned at said top end of said engine, a flywheel positioned on said output shaft at said second end thereof, and further including an electrical system, said system including a generator having a shaft extending therefrom generally parallel to said output shaft, a belt engaging said drive pulley and said shaft of said generator whereby said output shaft drives said generator, said drive pulley positioned above said camshaft drive mechanism at said top end of said engine and a starter motor for engaging said flywheel for starting said engine.
A watercraft powered by an outboard motor having an internal combustion engine powering a water propulsion device, said watercraft having an electrical system, said engine mounted within a cowling of said motor and having a block defining a crankcase at one side and having a head mounted thereto on another side and cooperating therewith to define at least two variable volume combustion chambers, at least one of said chambers in each of a first and a second bank of combustion chambers, said banks of combustion chambers generally oriented in a "V" configuration with a valley therebetween, said engine having an output shaft extending generally vertically such that a first end thereof extends beyond a top end of said engine and a second end thereof extends beyond a bottom end of said engine for driving said water propulsion device, a belt drive positioned on said first end of said output shaft, a flywheel positioned on said output shaft, and further including an electrical system, said system including a generator having a shaft extending therefrom, said generator positioned alongside said engine near said crankcase and opposite said valley with said shaft of said generator extending generally parallel to said output shaft, a belt engaging said belt drive and said shaft of said generator whereby said output shaft drives said generator, and said electrical system further including a starter motor for engaging said flywheel for starting said engine.
