| Running a 200 khz transducer on the back of a new Lund 1750 Fisherman. It is mounted on a plate on the transom. It is located more than one foot from the motor.
It is connected to a Lowrance 112C GPS/Sonar combo. All the latest updates are installed on the 112c.
My problem is that I get very inconsistent performance from the unit. Sitting still, drifting, low speed, high speed, sometimes it works and I get a usable signal, sometimes it does not. It was mounted by the dealer and it looked to me like it was mounted correctly. Since it was performing so poorly I asked them to move it down a bit which they did. The puck now sits below the bottom of the transom yet i still have the same problems.
My 520C that uses the transducer in the trolling motor works flawlessly. No, I am not getting signal overlap as the problems exist even when the front unit is off.
I can post a few pics of the mounting later today if that helps.
I have tried adjusting sensitivity etc. to no avail. I have a fair amount of experience with these units but am stumped. I can only think it is:
1) bad wiring
2)bad transducer
3) bad mounting (perhaps the hull on this boat requires a different mounting strategy to overcome the hull rivets?)
Any insight or past experience would be appreciated.

Location: Waukesha Wisconsin | Is it possible to hook up unit to front of boat to see if you can isolate problems? If it works there, I'd say it is the transducer. If it doesn't work there I'd say it is the new software. There have been problems with the updating.

Are you saying that it doesn't work sometimes while standing still or drifting?
Looking at picture, I'd be very concerned with knocking that transducer off when the time comes that you drive up too far.
Are there rivets in front of transducer, can't tell from picture.
Look at the back of your boat when someone else is driving and you are on plane. If that transducer out of the water? Are you getting major spray from that transducer when you are going all out?
Did you do the update or the dealer? |
