thanks for your suggestions that are very help-full to me. Indeed as you may understand our SM Desiree is quite 20 years old and her electronic has the same age also if we have always maintained it substituting time by time the broken components of the system. In any case the Hydra 2000 cpu at present is the main cpu that acquires data from the different sensors among which there is also the sonic speed one and all is perfectly functioning except the speed. If it will be possible I think that the substitution of the sonic speed sensor is at present the best solution because it is compatibility with the Hydra 2000 CPU . The use of different more advanced and updated sensors does not ensure this compatibility due the interaction with the old system. I am also far from the boat ( Milan) and the boat is in Naples. This attached picture shows what you can see on the keel i.e. the the hole of the aft sensor or more precisely the hole that presumably were occupied by the head of the sensor that we lost. What is unclear to me is if the hole in the keel was only occupied by a neoprene cap or what we have lost is a sensible part of the sensor. In this second case will be necessary to replace the sensor otherwise we can try to add a neoprene cap and try to set the gain on the sensor cpu. Do you have some suggestions and ideas about ? again thanks cheers marco
