This is very true. My generator sound box was mounted directly to a flat wooden area on my boat, and that big wooden area acted like a speaker transmitting the vibration all over the boat. I used some of Soundown’s isolating mounts underneath the gen box and it made a huge difference. The generator itself inside he sound box has typical rubber engine mounts but they transmit much of the vibration unlike these well engineered Soundown mounts.
