An underwater exhaust system and method which includes an exhaust valve having a sealing edge, an exhaust outlet for exiting an exhaust gas, and a projection for directing water flow away from the exhaust valve. The exhaust valve includes a valve head and a valve stem, the valve stem being coupled with the valve head. The system and method prevent a siphoning effect, whereby leakage of water into the exhaust valve is minimized or prevented.
