    Default Dynamat Noise Reduction Install - Craz

    I installed a Fresh Air Exhaust to my 2017 Craz expect the same noise reduction as my previous Moombas, however this was not the case. This Craz was still loud as hell even with the FEA, we'd still have to yell over the engine noise or turn up the music volume. Not what I wanted.

    I was pretty skeptical about the amount of noise reduction from installing Dynamat, but overall it really seemed to help.

    The Dynmat adds heft/thickness/sound deadening to the engine compartment.


    1. Removed the carpet from the backside of the bench seat engine compartment.
    2. Installed 2 layers of Dynamat, then 1 layer of Dynapad, then reinstalled the carpet using contact cement.
    3. Repeat the same layers for the lower bilge access panel - (This is where a lot of noise comes from).
    4. Used the leftovers to cover the engine panel dividers.

    $278.24 for the materials and 2-3 hours for the install.

    I did similar on the new boat, but just used cheap amazon sound deadening mat. Put it in the transmission access area and the panel between the rear seat and engine. Made a big difference and only spent around $50. Figured the carpeted panels were insulated enough. Now, with FAE and the mat, at 30mph can carry on a conversation with the windshield closed.

    I literally just did this today, but I just used Noico on the transmission cover. I removed it and put the sound deadener all over the inside of it. I also bought a waterproof adhesive foam from Noico (both from Amazon) but I wanted to see if just the 1st layer would be enough.

    I will contemplate pulling the carpet and doing the back seat wall too but that is going to be a far bigger job.
