Insulation on Engine cover

[Bradski]

My foam insulation under my engine covering is falling like snow in Colorado. Anyone have any tips for a replacement product? Where did you find the material?

West Marine. Noise reducing insulation.

I just bought the I/O foil-backed noise reduction kit from overtons and plan to redo my insulation before it's warm enough to ski. There's a nice little how-to on the MBO Discussion Board

Motor Box Noise Reduction Installation How-to

Well Doug the Malibu people should know they are the loudest boats around. I was lucky my factory foam in the engine compartment held up well. I reglued 1 section in 12 years. 3m spray glue works well. Get those projects done now cause soon you'll be doing those Dad projects.

No doubt. Interestingly, it appears that Malibu does not offer the sound reinforcement as standard equipment, but as an option.

mine did the same and I removed it all and had LineX sprayed in.

Actually made a slight improvement over the foam, and looks MUCH better.

Looks good, JR.

Thats great, I know a guy that did that to whole inside of a jeep. Now he can hear the stereo.

HUH? I can't hear you.... let me turn down the stereo in my Jeep

I'm Herculining my Jeep's tub this summer. Of course, I've been saying that for 2 years now. Maybe I'll actually get to it this summer!

JR--Can you give me a ball park figure of what the cost? Also, did it really make a difference quieting the engine. Thanks.

If I remember correctly, the quote was $400 un-prepped and $100 prepped.

So, I scraped, scraped, scraped and scraped the insulation and glue off of the interior of the engine cover.

I used the guys at Line-X, and it turned out great. In and out in about an hour.

Just got my box back from the upholstery shop. Yeah, I decided I hate cutting patters and got them to cut and install the foam. I think it looks pretty good though. Snapped a couple of pics before I left the house after lunch.

I did the prep work like JR (and with price in mind). The foam came off really easily as its apt to do after 12 years. Instead of scraping, I used an adhesive remover called "Goof Off" that I picked up at Lowes. Then I took it to the car wash and hit it it some soap and water to get the Goof Off off. Shop vac'd and dried it, then off to the upholstery shop. Total cost was about $200 ($79 for the foam, adhesive and foil tape and $125 for the labor). I still have to attach some foam to the screen beneath the drink holders.

The hardest part was getting the motorbox off. Thanks, George, for the tip about pulling the floor up.

Here's the foam (disected). Much thicker than stock.

Per George's instructions, I unscrewed the floor plate and rested it on the manifold risers. This made it much easier to get to the lock nuts securing the motorbox.

Here's the finished product (sans the screen under theh cupholders).
