What are you referring to when saying "shifters?" You're not talking about the throttle I don't think. I thought you were talking about the paddles, but you said you don't have those. I have a feeling it's obvious and I'm just missing something.
I do have the paddles. There are two ways to enable the DriveX mode, through a touchscreen toggle that switches from normal, to single lever (for syncing both engines while going fast), and DriveX. You must be in neutral to change modes. You can also toggle DriveX to normal mode with a physical button on the helm/wheel. Are they called helms on boats this small?
I will try in neutral, but I'm pretty sure on my boat you can only engage No Wake mode when clutch ahead. Going to neutral will turn it off and not allow it to engage. And if you push the throttles much past clutch ahead, No Wake mode turns off. I'm not sure what the difference is in No Wake mode and just pushing the throttles ahead a little more than clutch ahead. But I like that mode because I can engage it and feel at ease that I'm not going too fast through a No Wake zone. Although one buddy of mine, who is a long-time boater, thinks No Wake 3 creates too much wake.
