Dear Michele we did last year because our probe failed and I have tried with success  to replace the older one instead to put a new probe for several  reasons  . We  replaced ( my sailor man didi)  both the sensors  because we had to buy for about 300 US $ .  The cables run into a dedicated pipelines ( you may  easily see upper part of the one relative to the probe that look forward ) just in the compartment below the table dinette where you will see the cable inside a transparent pipe.  
 You can exract the probe and cable from the housing in the keel using a witness cable  and insert the new one pulling the witness cable from inside. You need to seel the probe in the keel with neoprene .  Check that the reading geometry of the front and rear probe is the same. 
I hope this may help

Hello and good evening from Rome
This summer I experienced  on  my SM2000 some troubles with the reading of the B&G speedometer.
I saw the documents in the files section, but there is not indication about how to replace them.
 I have to replace the sensors (that I have found in Ebay) but I'm not sure that this is an easy work ....especially to remove the old ones. Does anyone did this job before? I'm very scared about the sensor on the keel....I have seen that the sensors are two little plastic tubes but I don't know how they are fixed to the boat because there is no o'rings on the tube so I assumed that the tube is fixed with resin to the hull and to the keel....
If possible I prefer to replace the sonic speed sensors and don't do a new hole to instal a new sensor; for that reason I will be happy to receive comments from you
Thanks in advance
