Abstract
An outboard motor has an engine, a cowling for accommodating the engine, and an air duct for introducing ambient air into the cowling 11. An air filter is provided in the air duct. One or more sensors detect when the air filter is clogged. When air filter clogging is detected, a warning signal is triggered.
