Really? I am a little confused then. My boat at neutral and just over idle sounds absolutely amazing.....deep and loud, but not obnoxious. At speed it emits a nice deep tone, but is almost too quiet for a performance boat.
I had assumed it was loud at idle because the ST was empty of water, and quiet under power because it was full of water muffling things down......????

The steam is fine no worries. On my 336 with 525 SC's they steam with the box on. When I take the box off no steam at all. Here is why, water builds up in the box and sits in there. When the hot exaust hits the cold water it caused steam. This is normal. At idle the water fills up to make the boat quiet. When I am doing 80 -90 it blows the water out and is louder.
