Interestingly enough, what is called a stator in some Mercury Marine models is now called an alternator by Mercury Marine for the batteryless EFI models.
The stator being a part all alternators of course.
I am now wondering if these batteryless EFI's are inherently harder to pull start than non EFI models. It takes some mechanical energy to create the electrical energy needed to operate the ECU and electric fuel pump.
This thread talks about using an electric drill motor to crank the motor.

I agree that motors can be like living animals. Each having their own preferences as to how they like to wake up.
Since your model does not use a battery it relies upon the alternator to generate the electrical power needed by the ECU and the electric fuel pump. Permanent magnet alternators...
Running a drill motor, or pulling a start cord, more slowly is counter intuitive to my thinking.
Pull the cord more slowly and let us know what the result is please.
Voltage is a function of the speed of a magnet passing by a coil. Amongst other variables. Distance between a magnet and the coil being another.
.3 inch gap for the sensor seems to be abnormal. What does your SM specify?
0.6 volts seems low. Is that peak voltage or RMS voltage? What does your...
