Positive pressure is used to induce the flow of a liquid lubricant from a crankcase and through a drain conduit so that used oil can be removed from the engine and collected in a container during an oil change procedure. Positive pressure is introduced into the crankcase, and into an ullage region above the liquid lubricant, by the use of an inlet valve that can be attached to a cam cover to replace a PCV valve temporarily during the oil change.

Method for pneumatically removing oil from an engine

An exhaust system for a marine propulsion system includes first through fifth exhaust conduit members, including a pair of serially connected marine exhaust elbows laterally spanning the engine.

Exhaust system for a marine engine

A lubrication system for an in-line engine which has a piston symmetry plane that is tilted relative to a vertical plane is provided with an oil pan and windage tray that facilitates the transfer of oil from a rotating crankshaft to the oil pan without excessive aeration. In addition, it facilitates the removal of entrained air from liquid oil as it passes from the crankshaft to a pool of oil collected in an oil pan. A windage tray is provided with a louver structure and a louver opening structure that assists this passage of oil droplets without undue aeration being caused.
