Abstract
An electrically powered automatic choke system for a turnkey outboard motor has a thermostatic override switch. The automatic choke feature is often not necessary, and sometimes not even desirable, when restarting the engine. The thermostatic override switch prevents the automatic choke from closing carburetor choke shutters when the ambient temperature near the engine under the cowl exceeds a choke deactivation temperature. A switch assembly is provided to retrofit engines on existing outboard motors.
