    1200 DI out of water idle speed

    Curious as to what out of water idle speed is common on the 1200 DI engine. I am getting just over 1000 rpm on the tach. seems like is should be higher.

    Unlike carbureted machines which rev higher with no load on the jet pump, the Ficht electronic EMM controls idle speed precisely, in or out of the water, and adjusts the fuel flow to the injectors to maintain the idle RPM.

    Your idle RPM sounds about right.
