Ok, the engine cover on my I/O needs to be repaired/replaced. I started looking around to find a fibrglass from other boat so I can use it on my even if I had to do some mods to it, but it is worthless. Nothing that will match and anything that matches is all crappy looking. So, I'm going to to a new one for it.

These are the materials I'm thinking about.
1. Pressure threated 3/8 plywood
2. Plastic Water Ressitant Sheet (sell at Lowes)
3. Resine
4. Poly 2-part Paint
5. Insulation

1. Make the box out the plywood with SS screws
2. Cover the whole box with resine and let it dry
3. Cover the box with the plastic sheet and of course cut it to fit.
4. Paint inside and woden exposed sides with poly paint.
5. Cut holes for the 4 cup holders
6. Install insulation material inside the cover (dunno what to use for this)
7. Install on boat.

Any better ideas? Thank you so much everyone.
 
You are right on target. Lowe's has engine insulation that a lot of the local racers use. This month's PBR has a paint that has noise insulation qualities that they highly recommend. Expensive, but very effective according to PBR.
 
OH that was a joke! I went to lowes and when I asked the guy for insulation, he sent me to the r33 section (walls and cealings) I'm like "Noooo Homes....not that type' I'm looking for the same type or similar as the one underneath the hood of your car. He was like 'uhhh...u have to go to a auto supply'...I'm like...whatever...cant mention car or boat to one of these suckers that they want to send you to a marine or autozone.
 
If you find insulation for the engine compartment, let me know where and what kind you use. Mine is in need of replacement.

Thanks !

Pabst Blue Ribbon. It's what I was drinking when I posted....;)

PBR = Powerboat Reports. It's like a Consumer's Reports for boaters. No advertising, therefore no payola to worry about. I have enjoyed the magazine on and off for the last 15+ years.

The paint is called Silent Running and the website is:

Cost is $120 per gallon

Nothing in this for me. I have no affiliation with them.

Pressure treated plywood and resin?
Uhm, marine plywood would be my preference.
Or just the best grade they sell at the lumberyard.
Using some cloth with that resin wouldn't be a bad idea either.....

Read this before that "pressure treated" idea goes any further:

I don't even cut the stuff myself.....

From another site:

For use in boat manufacturing, the redrying of the treated plywood is essential to good performance when laminating with fiberglass. Treated plywood purchased from lumber yards is often used in construction applications and is not necessarily re-dried after treatment. It is essential for boat manufacturers to specify redrying.

At this point I'll suggest Douglas Fir.
 
I bought some marine plywood from Lowe's, who special ordered it, in case you're having trouble locating some. The sheet I got was great for a floor job I did on my boat and cost quite a bit less than other suppliers I checked with.

I'd stay away from pressure treated in a marine environment. If you're on a budget, you could use regular plywood and coat it with a fiberglass compound material, sand and paint with a marine grade paint. Make sure both sides of the plywood have equal amounts of fiberglass, paint, etc (to prevent cupping) and make a sturdy frame.
 
Grax, you're going to love this.....I work for a company that makes those underhood pads on cars. I can get you some of it, but it will cost $$$ to ship. Lowes sells an insulation product that will work as good or better. It is basically bubble pack with foil on both sides. I think that it is used for hot water tanks.
 
google "Soundown" they make the proper stuff as far as the insulation part is concerned.

I am just finishing install of Sounddown in the engine box of my little Albin diesel trawler. The install was easy. Can't report on results yet, since I haven't moved the box back to the boat from the shop. I'll post results when I have somethng to report.
 
hahaha! Ok...this is great!
BillM2 - I think we have a provider for the insulation. Look zeezer's post. Let's find out.
KiDa - Yeh, I think I'm going to find another silent solution. I'm not about to pay 120.00 for a galon of paint. I'll take a ML (Miller Light)
Grady - No MORE pressure treated, going with the regular 1/2 plywood covered with fiberglass.
BillM2 - I'm going to find out about ordering the marine plywood from Lowes to see how much it is.
Zeezer - Talk to me, how much are we talk about on the shipping. Email me at graxirena**gmail.com, we'll talk.
Orcabait - soundown? I think it is too much $ for what I need.

Thanks guys...
 
I would dry fit the box before covering it with any fiberglass or resin. When you do so, come equiped with a good belt sander, block shaver, and block plane. Then you can make sure you have good tight fit all around.
