An intake system for an engine arranged to be positioned within a cowling of an outboard motor for powering a water propulsion device of the motor is disclosed. Preferably, the engine is of the "V"-type, having first and second banks defined by first and second cylinder heads connected to a cylinder block, and having a crankcase or second end positioned opposite the heads and facing the watercraft. Each bank contains at least one combustion chamber, and the banks define a valley extending therebetween along a length of the engine. An intake system is positioned at the second end of the engine and comprises a surge tank corresponding to each bank, an intake passage leading from each surge tank to the cylinders of its respective bank, and a throttle body having an air inlet and a branch passage leading to each surge tank. An engine auxiliary component is positioned above or below the throttle body of the intake system.
