Abstract
An idle exhaust relief passage is provided with a valve that can inhibit flow through the passage in response to certain operating conditions of an engine of an outboard motor. More particularly, operation above a predetermined threshold can be used to inhibit flow through the idle exhaust relief passage. A valve, configured for this purpose, can be a flapper valve.
