Generator quieting
I have a Honda 3000 EM, I am looking for some ideas to quiet it down. Anyone had success with this, want to share some ideas?

I refer back to your's and other's pictures as I work. I am making good progress on mine and at the point to add the foam for the generator seal at exhaust end on mine and realized you used the foam without the decoupler layer in it! It appears the foam I have will not make a good seal.

What foam are you using? If it is the Soundown and you are curving the 3/16" board that it is mounted to it should make a great seal. You will want to position the round furniture insets that the EU2000i feet set into so that the generator snugs up tight to the foam and will not slide away from it.
Soundown sells different foams. I did not pay close enough attention in my web wanderings.
I believe you have Soundown "acoustic" 1/2" $30 sheet. I bought Soundown insulation barrier, it is 2 pieces of foam with a loaded vinyl piece in the middle at $70 sheet, still 1/2".It is not as flexible as the acoustic. I believe "Jorgenson" used the insulation barrier.
I did use the 3/16" ply good idea, had to buy a 4X8 sheet to get 1 small piece, the rest will not go to waste.
I like the rubber cup idea but not entirely sold on it and still looking.
I am experimenting with different configurations on the exhaust ducting but not getting as low a temp on the genset as I would like even with the fans.
Thanks Jim
