Helix 7 Problem

[Caseyd]

I recently got a Helix 7 G2N.  Great graph and absolutely love it.  Only complaint, the transducer and power cables shake free when running in choppy water.  Didn't know if anyone else experienced this and if anyone had any suggestions on how to keep them attached.

Both wires to my graph are in a loom with some slack so they point straight in with a gentle curve. Bushing going thru the glass so there is zero "pull" on them. Perhaps having them bound together makes enough misalignment to keep them anchored?
