I have a problem with one of my d6's intermitently.
when I power up onto the plane sometimes my starboard engine sounds the alarm and the caution light goes on and it goes into limp home mode. if I turn the engine off and on it is fine again. One thing I have noticed is that the volt meters seem to go up and down iraticly at full throttle they move a distance of about half the the gauge.
when I bought the boat it had dead batterries which I have on charge all the time now but they dont turn the engine over very fast. could this be related to the problem?.
