My boat has ZF Mathers controls. The previous owner did a lot of research on them and documented all of it. He had the hardware updated at the factory to address the potential runaway fault as described in the first post. If you have them and are concerned, I would recommend that you contact the manufacturer and ask them if the hardware you have is subject to safety hazards. They have a lot of incentive to make sure the controls work and based on the printed emails I have for my boat, they are responsive. I love the shifters. Mine have their own dedicated batteries (2 6V GC in series) so that there is no chance of a voltage dip from some other load.
