Idle relief mufflers are configured to discharge exhaust gases from an outboard motor to atmosphere surrounding the outboard motor when an internal combustion engine of the outboard motor is operated at idle and at low speeds. The idle relief mufflers comprise a housing having an open interior, an inlet port configured to convey the exhaust gases to the open interior, and an outlet port configured to discharge the exhaust gases from the open interior. An exhaust grommet is connected to the outlet port. The exhaust grommet comprises a body that is configured to engage with a cowl of the outboard motor and an extension that extends through the outlet port and protrudes into the open interior. The extension and the body together define a through-bore that is configured to convey the exhaust gases from the open interior to the atmosphere.
