Hello all! I have twin 350 Mercruiser Mags manufactured in 2014. I have electronic controls and was successfully using single-lever mode (by pressing the "1 lever" button) but it has stopped working. It lights up but moving the throttle does nothing. Taking the boat out of single-lever mode, I can apply throttle to either engine independently or together. Its not an issue providing me from running but out of convenience it would be great to fix it as I have a long trip this weekend and don't want to bring the boat in for the dealer and risk missing the trip over a non-running issue. Any thoughts or tips would be greatly appreciated. Thank you!!
