What type of foam should I use inside the motor cover?

[KM7]

This is on a Four Winns Horizon 200 with a 5.8 V8. The foam in there now is starting to come off. I might as well replace it. It can't be very expensive. ( yea, I know. It's a BOAT!)
Of course the objective of the foam is to reduce the sound of the motor, so I want to use the right foam.

I can't just use any sound deadening foam because of the heat under the cover and the risk of fire.

Any recommendations?

Youre not gonna get a fire in the doghouse, regardless of what you use, pretty much, if your engine is marine, But any foil coated deadening material will work, depending on budget as always.
