| Just a quick question. I have a Furuno FCV-582L bottom finder on my Trophy. The transducer is mounted on the starboard side of the transom, about 1 foot to the right of the outboard. Now I know that once you get up to a certain speed, all sounders will lose their depth finding,but mine seems to cut out at about 6 to 10 mph, which is kinda slow cruising speed. This makes it kinda scary when Im in the bay getting close to shore, as the depths get really shallow really fast. I can slow back down and about stop and it will reaquire the bottom. Do you guys think that maybe the transducer is mounted too close to the motor wash making to lose signal too fast, or is this what everybody goes through? By the way, I love the sounder and will not replace it at this point. Thanks in advance Mike

| Yes I think that is the problem. We had a reg 582 on my buddies boat and it read wide open.

Generally speaking, the closer to the keel, the better the marking capabilities at higher speed.

| After having repowered my boat, (going from twins to a single). I moved my transducer and was having the same problem as you described. It turns out that when I attached my transducer the second time I did not have it low enough. I adjusted it down about a 1/2", to where the transducer was about 1/2" below the hull and the problem was corrected. It went from cutting out at 7 or 8 knots to now reading at up to 40 knots.

Good info..I may try to drop it down into the water a little more and see if it will read better. Either way, if I can just get it to read at about 25 mph, that would be fine.

you should not lose the bottom at any speed going forward. It needs to be properly adjusted.
