Foam in cowling

[jspringator]

According to Mastertech:

If the inside of your motor cover has a foam sound blanket and you use the motor in saltwater, see if it is a closed cell foam, if not RIP IT OUT! Salt is hygroscopic, that is it attracts moisture and the 2 do a great job of eating up the motor. All OMC motors use cheap foam.

My 25, which the seller says doesn't have a proper year cowling, has foam described in the above quote. Interestingly enough, my 6hp has closed cell foam. Is there any way to seal the foam up with paint or something? If I rip it out, what can I use to replace it?

Re: Foam in cowling

I have never actually tried this but maybe Thompsons water seal?

Seems like it would get sucked into the foam and seal it and that has to be easier than trying to tear out foam.
