Hi stedj,
Could be that the transducer has slipped a little too high on the transom and is not getting a smooth flow of water or cavitation (water turbulance from the prop) could be interfering with the readings. Electrical interference (from the alternator, bilge pump etc.) can also be a factor.

i had exactly the same problem solved it by moving the transducer right over on the transform almost touching the tube edge ,i was advised by seamark nunn where i purchased it to get it as far away as poss from the prop !
