If you are confident that this effect comes from the cable, you could
certainly minimize the problem by cutting some out. But as mentioned
already, the extra length can be useful.
If you're trying to minimize this microphonic effect, you probably have
it wired into your XLR plug the best way. You might try connecting the
signal between pins 2 and 3. I am not familiar with these hydrophones,
but I suspect that you'd get a lot better low-frequency response and
possibly lower noise if you use an impedance transformer or DI box
between the hydrophones and preamp.
