The hottest air/fumes in the engine compartment will be at the top while the engine is operating. One wants to remove that and have it replaced by cooler clean air that will be drawn into the bottom of the compartment by static air pressure. In most cases, you will want roughly twice as much intake vent area as you have discharge through a properly functioning vent/blower. If your engine is gasoline powered, you may need an intermittent blower/vent to the bottom of the compartment to run for a few minutes before attempting to start the engine as a matter of safety. Unless your boat has some serious defects, there will be no way that Propane fumes can reach the engine space. If they can, however, you have much more to be concerned about than where the exhaust vent is positioned.
