MerCruiser's exclusive Turn Key Starting system is standard on all carbureted engines. This patented feature eliminates the hassle of starting a cold engine. Simply turn the key. No choke, no pumping or priming required. This means that the entire MerCruiser gas line-up features Turn Key Starting. No other engine manufacturer can match that.
