Depth display The depth reading from the 498 is about three feet different from the reading of the depth gage on the boat which I know is correct. At high speed the 498 doesn't record dept also.

When my depth finder acted like this I found out it was the sender that had not done well over the winter and was giving me false readings especially when the boat was at speed. The sender and cable only cost around 30 or $40. The hard part was since I have a pontoon boat getting under the Pontoon and replacing the wire in the spring when the water was cold.

If the transducer is out of the water, you will not get a reading and see the flashing depth. You should hear and feel the clicking in the transducer when out of the water and working properly. Are you getting a temp reading when out of the water?

Lowrance depth finder missing adapter cable

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.

Hi- I have a 1996 Four winns boat with the same problem. I believe we are missing an adapter cable which goes from the depth cable to the instrument panel. I have not been able to locate this cable yet. If I find it I will let you know and can you do the same for me if you locate one?

Lowrance x96 does not function after 20 feet depth

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.

Garmen 240 fishfinder

A test bucket wont work, A 200 khz transducer will generally not work in anything less than 2' of water, due to surface clutter. If the transducer is working, you should hear it make a ticking sound.

When you got the 17000 foot reading was your range set to auto?

How is the transducer situated on the boat? Sometimes turbulence and bubbles from the hull can cause erroneous readings, including unrealistic depths, or no depth at all. Stop the boat and turn off the engin e and anything electrical to see if problem repeats itself. If it only crops up when the boat is moving then it is most likely the transducer location.

Depth sounder problem

If the transducer is mounted off of level, an error is introduced due to angle. It is a fixed percent offset, say 10%. so 10 feet reads 11 and 100 reads 110. There is an offset function to read depth below ducer, depth below keel, and depth below waterline, but these are fixed amounts in feet, not a percentage. Look at the transducer when it is operating, boat angle considered.
