      Has anyone ever tried  that  rubberized  truck bedding spray  as a sound absorbant  for OB cowls.   My 7.5 Merc  is mssing  the usual  padding .  I do have sticky  foam  I could try  as a liner but spraying  a couple  of coats  of  rubber under the cowl may  dampen the sound just a well and  easier to  just spray on.

        Around 10 years ago, I used “Soundcoat” adhesive backed 1/2″ thick sound insulation on my 1990 Evinrude 15 cowl. It works well, and the job came out decent. It did, however, involve having to make a pattern, then using the pattern pieces as templates to cut 3 panels of the foam.

        It looks like the “Boom Mat” spray would be so much easier, and the fit would be custom. Not sure about the soundproofing effectiveness comparison.

          I did the pattern thing on a 9.5hp turtle years ago ..worked out ok  and I kept the templates.  This mid 70s  Merc  project would be even easier  design wise but…I am getting lazy !

          I will try 2 coats asa the temp gets warmer outside. (better half wants no sprays   in the house !!!)

            That product is showing as $27.99 on that Amazon link.  Other sites have it from $11.00 or so.  I guess the Amazon link is the Canada Amazon and I guess they ship for free.

              agree lots of stuff on Amazon Canada  is cheaper at the store… free shipping usually boosts the price   and we pay PRIME $99/y for this free shipping 🙁   some items are worth  it but buyer beware all the time.

              ex : MXR2300  $500 generator  was cheap. on sale  and  delivered fast …. not a honda  at $2000 but good enugh  based on hundreds  of feedback.  time will tell.

              Honda stuff is good .. my snowblower from 2008 still looks  new  (with TLC)   and works fine (except belts of course)

              I saw  Teflon  snow blower spray for $30 on Amazon    $10  locally  !!!    Seller dropped his price     after I sent him info on my local price !!

              see 2  links    same product  !!

              btw   for my Merc 7.5  cowl……I ended up buying a similar product  with sound proofing specs  for  15$  🙂
