Hi Ian,

RV100s are sometimes mounted under the hull where there's a transom step, using our A80479 adaptor kit, but I don't know of anyone installing under the hull at the transom where there's no step. We don't tend to hear about the unusual installations however. We offer designed through-hull transducers (RV200 and RV300 ranges) for this purpose, and personally I always recommend through-hull transducers if one can be used.

I am guessing that the 'noise' isn't coming through transom vibration because of the different levels on the port and starboard SV views: I think that if it were a transom vibration problem then we'd see the same noise level on both sides. If I'm correct in saying this then moving the transducer further from the engine should reduce the noise level, or installing some sort of baffle. I think that we need to verify the diagnosis first though.

Regards,
Tom
