My very first V20, back in the early 80's, had an I/O engine. The engine cover had no insulation on the inside. (I don't know if it came from the factory that way or the PO had stripped it out). Anyway's I had that boat for several years and truthfully I didn't really notice the engine noise while running. Before you spend large amounts of cash I'd try it bare first and see if it's tolerable to you.
(Another idea would be to go to your local junk yard and look under the hoods of older cars. Auto manufacturers used to line the underside of hoods with a fiberglass mat for heat and noise abatement. The engine side had some kind of coating on it to resist engine grime as I recall. Just peal off what you need cut it to shape and glue it on your cover. Or check your local auto supplier and see if he has any that's new). Or you can check out this stuff. http://www.xtremediesel.com/thermote...FdeIswodQZcFWA
