A marine outboard motor (2) is provided with an internal combustion engine (30) comprising an engine block defining at least one cylinder(33a-33c), an air intake (93) configured to deliver a flow of air to the at least one cylinder; and an air intake duct (200) forming part of an air intake path for delivering the flow of air to the air intake. The engine further includes a flow sensing arrangement(210)located in theair intake duct and comprising a flow meter (211) configured to generate a signal indicative of a flow rate of the flow of air through the air intake duct, and a bluff body (212) located in the air intake duct upstream of the flow meter, wherein the flow meter is a vortex shedding flow meter.
