Try adjusting the trim or get the boats nose up even to the point of porpoise (I think thats how you spell it) if the signal improves with the nose up you may need to lower the transducer more than the manufacturer recommends. the slight looking foward will also help. My current sounder works pretty well up to about 25kn

Depth: Could be for a number of reasons, too deep for the sounder - check the manual for it's max depth. Dirty water, sounder unable to penetrate through to the bottom. Weed or other debris covering the transducer. Transducer on a swing mount & being pushed out of alignment then dropping back in once stopped.
Speed: Is the speed readout controlled by a GPS or paddlewheel? If it's GPS, check the power connection of the sounder, may be loose which would also cause the depth to 'drop out'. If it's paddlewheel, you're down to bad connections or faulty unit.

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.

I installed my Navman 4150 depth finder along with the Navman GPS unit when I purchased my Bayliner Trophy 20Ft. Offshore model. Everything was ok for one year and it has been downhill since then. Losing signal, unbelievable high depth ranges, blank periods, etc.. I now can't even get a reading tieded up at the dock. I am now giving up and shoping for a quality unit.. Cape Disappointment.........
