Abstract
An outboard drive is equipped with a water inlet located on a lower casing of the outboard drive. The lower casing includes a nacelle that houses a transmission and a propulsion shaft that are coupled to an engine through a drive train. The propulsion shaft rotates about a longitudinal axis that is aligned with a centerline of the nacelle. The water inlet is located on a front, cone-shaped nose of the nacelle, forward of the transmission and above the longitudinal axis of the of the propulsion shaft. The water inlet communicates with a water passage that guides cooling water to a water pump. The water passage is located in front of the transmission in order to increase the size of the water passage over prior water cooling systems of outboard drives.
