Breather structure for outboard motor

摘要

Several embodiments of lubricating and breather systems for outboard motors that provide effective oil separation and which permits the blow-by gases to flow in a direction the same as the lubricant return to the lubricant tank so as to avoid flow restriction. The blow-by gases are then discharged to the atmosphere through a conduit that is separate from any of the lubricant return conduits. Oil separating arrangements are disclosed as are various positions for the oil separator including in the cam chamber of the engine or in the lubricant tank.
