I am renewing the flooring, carpet and basically 80% of my 1996 Spectrums interior. Its semi intense. This is my first post on this forum however I have read through it many times in the past.

My boats got a ton of carpet glued over aluminum and wood from decking doors storage etc its going to be a fairly long winter project. Im up to the task but ive got questions and from what ive read there are a lot of does and donts that just arent clear to me.

First the flooring and all other plywood, Im planning on using marine plywood its rivited into aluminum bracing and I will most likely use rivits to resecure the new wood. Its got 5/8" plywood in now I dont think going to 3/4" will add to much weight but I also dont know. What your take on that. Then how to seal it some say not to use fiberglass as it may prevent the wood from drying out when it does get wet. So if thats the case seal it with epoxy or other and what types. Ive also read about drilling holes and sealing them before installing thepanels how important is that to some degree this usually becomes an issue because the holes may never line up. I have ideas about how to do this by drilling a couple of main holes and sealing them then working outwards from there drilling and sealing them as I go i can take a week or so to do this part, but Ive assembled a lot of things and its pretty hard to drill say 80 holes that wont be held in place until after those have been sealed I would expect most of them to be out of postition when i go together. Also should I leave any gaps between for expansion or but them tight or just flush. I do plan to fit them as well as possible before anchoring them.

Then on to carpet man are there a lot of choices thickness what weight backing to use the carpet makes folds over edges every where I read about a lot of carpet either not making the fold well and bonding being and issue if the carpets to stiff or thick and if its to thin then the backing shows through. What weight and is there a brand youd recomend. By a lot of corners and edges i mean a lot of edges and folds there are three edges that run the entire length of the boat another dozen on high traffic areas then every single door and cubby.

Also if it matters i live in the Northwest on the columbia river my boat sees hard rain and moisture 9 months a year its covered with a canvas cover but lives outside. Snow and ice three months of the year and blistering heat two months of the year. We also are big bulky fishermen that wear heavy shoes so a carpet that will hold up to that is a must. Then when its not fishing its dragging skiiers in swimsuits and bare feet so comfy is just about as important.

And to dive a little deeper into this which might need to go into engine repairs. The exhaust manifolds look like a simple task to remove and inspect for possible issues with the transom covers removed should i remove them while its apart or is it best to just leave them alone. One of my buddies 5.7 had a failure here and its now looking like an engine repalcement. However my boats seen salt water three times and within 24 hours it was ran in fresh water long enough to have flushed it farily well. Im in this boat for the long haul its basically perfect for my needs I have owned it since it was 5 months old and plan to keep it alive until mercruiser parts are no longer available for it. i wont say money is no object but its less of an object fixing this than say buying a $25,000 to $30,000 boat to replace it. Im also a fairly creative individual so none of this is going to overwhelm me. But I want to make sure i make the right descisions.

Its now partially dismantled in the garage drying out this is the first time my boats been out of commision for more than 5 days i already feel naked. LOL. my starter went out this summer took 5 days to get the right one. Funny i remember that. And i wont tell you this thing is my life its just a tool to make living through these dark wet winters worth it. LOL. Any way i have until the last week in March to be assembled and ready for salmon.

Thanks for your time and tips.

Re: Boat carpet and flooring tons of questions

I would also suggest going with 3/4" marine plywood. We have a plywood specialty store in our town that carries all kinds and sizes of plywood. Such a supplier can help you choose the plywood best for your application.

Rivets may work you to death, as they require holes be drilled first. Why don't you attach your floor with stainless screws--available @ Fastenal in bulk? Maybe they've got self tapping screws.

Google "Marine carpet" to find everything you never wanted to know about boat carpeting. Other sources are PontoonStuff.com and GreatLakesSkipper.com. I've heard really nice things about the new textured heavy vinyl for marine use, and you might consider it due to your rainy region. Anyway it goes, you must use the proper mastic (glue) and roll down the floor with a heavy metal vinyl floor roller--available at rental yards.

Exhaust manifolds are no big deal if your engine(s) are easy to get to. They're something to watch closely on older boats, as they can rust enough for water to get into your engine. The oil pan tells whether there's a problem. If this boat suits your needs, there's no reason not to treat it with respect and maintain it to perfection.

It wasn't clear what kind of drive your boat has. If you've got I/O's, I suggest you drop the lower units and take them in to be vacuum and pressure tested. Outdrive seals cause problems, especially on aging boats. I toasted my lower unit this year due to ignoring maintenance. They're just not that hard to change the grease on.

Re: Boat carpet and flooring tons of questions

As far as the weight difference between 5/8 and 3/4" plywood, the 3/4" will be about 12.5 lbs heavier per 4x8' sheet. Plywood is 25 lbs. per 1/4" thickness per 4x8' sheet.

MDO (medium density overlay) plywood is a good decking choice for boats, cheaper than marine plywood and made for exposure to moisture. It's used in exterior sign making and concrete form construction to hold the wet concrete in place until it sets.

Epoxy resin is best for sealing plywood, and if you have a lot of square footage to seal it is well worth ordering it online.

Removing old carpet adhesive from aluminum or wood is a chore, and I haven't heard of an easy way to do it yet. For aluminum, a 30 grit sanding disc on an angle grinder will take it off, but it's pretty messy. I found that using CitrusStrip paint stripper to soften it up and then using a 2" wood chisel to scrape it off to be much cleaner. Then use a wire cup brush on an angle grinder to remove any residue and give the aluminum a nice brushed finish for the new adhesive to grip. The CitrusStrip is nonflammable and doesn't have noxious fumes (smells like oranges) so it can be used indoors. To remove old adhesive from wood a belt sander with a 30 grit belt works well, but is messy.

I personally feel that carpet has no place in a boat, it absorbs and retains moisture which promotes mildew growth and rot. I like a water shedding deck finish like marine vinyl or a "paint on" finish.

I removed the carpet from my boat and installed marine vinyl instead... I absolutely love it! It cleans up very easily and looks brand new after each cleaning with no stains to worry about, dried fish blood doesn't even stain it and washes right off.

This is what my boat looked like before and after the change from carpet to vinyl:

Re: Boat carpet and flooring tons of questions

A little more update and a lot more questions.
First my boats clearly broke now. LOL. Its all good while i will be the first to tell you this is for a fact fairly hefty proceedure my friends will tell you i am the man for the job. I have enough to keep me busy without boat renovations. I own two auto repair shops and build cabinets for a hobby and have my own commercial sewing machine so if I do in fact fail at this its time to quit my day job and take up drinking again. But my boats definately grounded for a while. I do however not procrastinate and it will be water ready by March.

Ok I have commited to replacing the entire interior. The more I dug the worse it got. it was coming apart either with my help or without. Ill get pictures over the weekend at this point its a pile of carpet a dozen piles of this and that and a mountain of rotted plywood and broken screws and rivets.

I am going to use marine ply in 3/4" thickness my wife works for a lumber yard so my cost on it vs MDO or New wood is irrelivent given the scope and costs of this whole thing. it had 5/8" plywood before but it runs 55 MPH when propped right so a mile lost to weight wont hurt plus Ive been lugging around an extra 200 pounds in water logged plywood for 5 years Ill probably gain a MPH when its done.

Ok I need to coat the plywood in a marine epoxy resin right? any brands i should or should not use theres more suppliers than there are boats. I think I will need 4 gallons I have a lot to cover. It may take less. But I bet four is what I will end up buying.

Im thinking about doing the roll on or spray on coatings for the sidewall and top railing which is 6 inches wide. I sit on these areas and when its cold and raining I think even vinyl will not shed water as well as these coatings. Plus theres are a ton of edges folding and getting vinyl to adhere to can be a pain. And if I do wear through a spot I can recoat right.

And Im pretty much sold on vinyl flooring now over carpet its going in the main floor and the bow area decking. So no more carpet. Im going with a bland grey or off white color, samples from a few sources are now in route. The wifes thinking my boats going to be dull now. It was teal with red patches and welt chord here and there. So be it. its a functional thing it will look great and hold up and clean up well in these colors. Should not be to hot when its really hot. And were fishing more and more died baits and i really work the die in hard. My bait looks like lures.

I have solved my imediate mental agony through this. i mentioned my boats broke now. Sorry i might overstate this at times. Well i bought a really nice aluminum drift boat over the weekend and can still fish if the time allows it. My wife doesnt know about it yet I plan to drag it home christmass eve and put a bow on it and then go wow look what Santa brought me. I wonder if I will have to sleep in the camper or if she will relsih my new boat as much as I do. I pulled up in Costco parking lot on my way home with it over the weekend and this guy pulls in to talk to me about my Beautiful drift boat. Its 20 years old thick aluminum and like new been sitting in a garage for the last 10 years. last registered in 2003. \


Well maybe you can help with my new list of questions thanks

Re: Boat carpet and flooring tons of questions

What is your location LSG? This will help with your choice of epoxy.

I like the medium 3:1 635 thin epoxy from here:
Epoxy :?Epoxy Resins and Hardeners
... when working in warm conditions, but if you're going to be working in cool conditions you may want to choose the fast 4:1 mix.

I'd start with 2 gallons, the 2 gallon kit is 2 gallons of resin plus 85 oz. of hardener.
