Fishley,
so how do you ground it too the motor?
I've also been thinking (I know its dangerous, as you will see). I've been playing around a lot with the finder while trolling and while vert jigging. I am not absolutely sure that I have tried the 200 Khz mode with the motor turned off. I know the 200 Khz mode doesn't work (too much clutter) while the motor is running and I know the 50 Khz works great weather the motor is on or off. So anyway as I was thinking I remembered that I already have a depth sounder on the boat (came stock with the boat and installed in the dash). I began to wonder if I was getting some interference between that depth sounder and my fishfinder. So I pulled out the boats depth sounder manual only to find that the boats built in transducer is a 200 Khz transducer. So now I am really wondering if I have ever tried the finder in 200 Khz mode while the motor was NOT running (and therefore the boats sounder would also be off). I have done most of my playing around with the FF while trolling because once we found a school of fish and cut the motor to jig then I was too busy catching fish.
So I'm thinking I may be getting some interference from the other depth sounder when in the 200 Khz mode. I need to take the boat out again and try the finder in 200 Khz mode with the motor running (or even with the key turned on because that turns on the depth sounder) and with it off. If I get the interference with the key turned on then I have discovered my problem. If I don't get the clutter with the key turned on but do when I start the motor then maybe like fishley said I'm not grounded correctly. I can also try unplugging the boats depth sounder under the dash.
If it is the boats depth sounder interfering because they are both 200 KHZ then I will need to install a switch on the boats depth sounder so I can turn it off when I am using the boat for fishing (and therfore have my finder on the boat and hooked up) and then flip the switch back on when I am doing watersports with the family and don't have my finder on board.
I think there is smoke coming out my ears..... Am I thinking logically here?
