The latest trend in high buck Gov boats is to have a really Quiet genset ,
so they can sneak up on the little fisheys and do an acurate head count.
They mount the gen set on a set of soft mounts, which are conected to a metal box frame.
The box frame is then mounted to the hull with firmer mounts.
The interesting part is EACH corner of the frame are weighted with 10% of the gen sets weight.
Yes the frame weighs an extra 40% (plus what its made from) but weight doesnt count for much in a 300ft boat.
For a Lawn Tractor genset that only runs 500 -800lbs an extra 400 lbs or so to get really quiet might be worth the effort.
Not for me , as my air cooled OHNO on a service slide will never be "Quiet",
But for the folks that like the mental masterbation of 'THE BEST!!!" it might be an improvement.
Have fun,

Ah, Yes, The interesting, esoteric world of frequency dynamics.
Combined with a dynafocal mount installation, you could probably get away with alot less than 10% dampening weight per corner.
Abolute position would also be a factor. With Prof. Pejack's frequency recording equipment, you could probably find out whether 5# cranked to the right is better than 10# straight away from the corner
The lateral line on fishies is ALOT more sensitive than the human posterior! LOL!!
