ABSTRACT:
An arrangement for an engine positioned in a cowling of an outboard motor and having an output shaft arranged to drive a water propulsion device of the motor is disclosed. The engine has a first end and a second end and a centerline passing through the ends, at least one combustion chamber, an intake system positioned along a first side of the engine for delivering air to the combustion chamber, a lubricating system including an oil filter for delivering lubricant to the engine and an ignition system including an ignition coil for charging an ignition element corresponding to the combustion chamber. The ignition coil and oil filter are positioned along a second side of the engine opposite the intake system and arranged to reduce the transfer of heat from the filter to the coil, with the oil filter having an outermost portion which is positioned outwardly of the engine between the centerline and a second line which extends parallel to the centerline and passes through an outermost portion of the ignition coil.
