Old 2004 AR210 had engine bay going to powder. Stuff was a nasty mess. Got it pretty clean. Thinking about just leaving it out. How much difference would anyone care to guess it will make?IMG_20190621_115124.jpgIMG_20190619_125021.jpg

Ew. Nice job on the cleanup.

My guess would be that it will matter more on the sound front than you might realize. I put just simple egg crate foam on the sides of my engines and it made a notable difference. I am betting running without anything on the hatch will let you hear the engines pretty well...

But, before you do that, many have put soundproofing mat down first. As long as you have it all out and clean, I would do that.

Thanks for the input. I can appreciate the effects of a good sound mat. Light weight egg crate foam doesnt have enough mass to block noise. As easy it is to pull the engines I might run it without and if it's too obnoxious just lift them back out and do some sound matt.

Engines installed and put together. Should be ready to water test when I can get a chance. IMG_20190720_135542.jpgIMG_20190720_135040.jpg
