Abstract
A water cooling system for an outboard motor provides a water conduit that extends through both an idle exhaust relief passage and a primary exhaust passage. Water within the water conduit flows through first and second openings to distribute sprays or streams of water into first and second exhaust conduits which can be the primary and idle exhaust relief passages of an outboard motor.
