[font "Comic Sans MS"][black][size 3]You are definately getting interference from the depth sounder on your sonar if, in fact, they are the same frequency. Turning it off should solve your problem. If I run both my X98 Lowarance fishfinders on my boat at the same time, I also get interference. If I switch one to 200 khz and the other to 50 khz, the interference disappears.[/size][/black][/font]

[font "Comic Sans MS"][size 3][black]As far as your cabling goes, you do not have to ground to the motor. A good, clean, UNBROKEN ground to the battery is fine. If for some reason you think the motor is throwing back interference then try hooking up to a battery not connected to the motor. There really shouldn't be a problem. Also something to consider is where you have run you transducer cable. You should not run the transducer cable parallel with a battery cable, like your battery cables going to your motor. This can also cause electrical interference. Your transducer cable should be run away from the battery cables as much as possible. Hope this helps.[/black][/size][/font]
