Hello everyone.I work here in dubai as boat driver in watersports and we have two tige boat model 2008 and model 2010.Does anyone here can help me because our boat is on power but the screen where speed,temperatures and speed located is totally blackout but the engine is running.I tried to ask one of the technician here in dubai and he told me that its the boat gauge module have to be replaced?My boat gauge module is medallion 7021-00006-01.He also take a power from the positive line and connect it to the ignition switch and the screen is already working but the problem again is the rpm is not enough eventhough you put to the maximum speed.Also the cruise control is not working anymore.I want to ask if its because of the boat gauge module why rpm is not enough and cruise control is not working?
