A marine outboard motor (2) is provided with an internal combustion engine (100) comprising an engine block (110) defining at least one cylinder, an air intake (150) configured to deliver a flow of air to the at least one cylinder, a crankcase (140) in which a crankshaft (31) is mounted for rotation about a crankshaft axis (32) which is substantially vertical when the marine outboard is vertical, and a crankcase ventilation system (170) configured to vent blow-by gases from the crankcase and to supply vented blow-by gases to the air intake. The crankcase ventilation system comprises a lubricant separation chamber (180) for separating lubricant from the blow-by gases. The lubricant separation chamber is defined by the crankcase and extends along the length of the crankcase substantially parallel to the crankshaft axis.
