Your transducer needs to be adjusted so the return signal can be picked up. Some of these have to be super tuned to receive the signal. Also the transducer may be moving ever so slightly when the boat is traveling at speed. You may have some water turbulence interference all contibute to signal return.

Had the same issue with another brand. Turned out the transducer cable was picking up noise from other cables (power, trolling mtr. etc). Try moving the transducer cable away from any other cables. I put the cable in a 1/4 " plastic housing up to the point where it was above deck and it stopped all the strange stuff. Not sure about the temp issue??

I had the same problem and got the transducer changed. It now works perfectly. That could be the problem you are having... bad transducer.

I own a 1995 Four Winns and what you need is a Lowrance LSM-1 depth finder unit. It accepts the two pin lead from the transducer and send the depth reading to the dashboard display via the 6-pin connector. There is also a three wire harness (red/blk/wht) that connects to a power supply.

The reason I know all this is my depth finder fried a couple years ago so I removed the Lowrance LSM-1 from the boat in order to find a replacement. Unfortunately, this was an OEM part that is not available from Four Winns or any aftermarket source. Probably your best bet is to look in a boat salvage yard or purchase an aftermarket depth finder.
