I am currently having ignition issues with my 2006 38 sundancer. Once the boat is running the ignition will reboot itself. Meaning you hear the beeping sound when you put the ignition button at the helm in the on position prior to starting. All of the gauges on the port and Stbd engine go to the off position and then back to the position they were at prior to resetting. The port engine seems to cut off just for a brief second and then goes back on. The engines never quit. My mechanic is trying to separate the issue from the boat itself or mercruiser issue. We have yanked and pulled on all connections. Nothing is loose. We checked out the pin harness at the top of the port engine. Some times the port gauges will go completely dead and register off on the smart craft yet the engine stays on and running when underway or at the dock.
