I have a 2007 f150 that I bought new and within a few months thieves stole the cover and ss prop. I purchased a new replacement cover from Yamaha and noticed it does not come with any sound insulation and seems noisy compared to the original cover. I thought the original cover had insulation but did not have long enough to be sure. Do the f150 covers have sound insulation? Is there an aftermarket product that i could use on the inside of the new cover to lessen the engine noise? Thanks for your suggestions / help.
