Can someone tell me where the transducer for my bow mounted 787C2 is located. I have a new 08 Sabre FTD. Also, while on a recent trip to the lake I noticed over a 10 degree water temp difference between the 787 on the console vs the one at the bow, the bow being 10 degrees cooler. I know the temp sensor for the console unit is located at the base of my jackplate. Do they both use the same sensor and transducer?? Thanks in advance for the help.
