What is this and how do I get it out???

[Biggems]

Hey everybody,

I just got a new boat and want to take up the deck to inspect however the deck is fastened down with something that I am not sure what it is. I've taken some pictures so hopefully somebody can help me out. I think they might be some kind of rivet. I dont want to tear the deck up, just take it up, inspect, and put it back, if possible.

Thanks!

It's a pop rivet. You have to drill it out

It is a rivet. Just because you don't like it doesn't mean it's not there for a reason.

Before you "chuck up" your drill-THINK!

Some types of carpet will just shread to pieces if you touch it with a drill bit. If you really have to remove it,use a small chisel and chop it off,and push remainder down through the hole with a small punch.

Ayuh,.... It Don't work that way....

In order to disassebmle the deck enough to do a thorough Inspection,...
You'll be Replacing At Least the Carpet,....
Maybe More...

No disrespect intended, But,....
If you can't identify a Pop-Rivet,...
You're Probably in over your head....

If your hull is an entry level boat, it is more than likely that those "pop" rivets were not backed up with washers. This makes them a weak joining method and they tend to pull out, right through the fiberglass.

A "pop" rivet is primarily a rivet used where the back portion can not be reached or is "blind". It is a hollow tube with a flange on one end. In the center there is a "nail" with a slightly enlarged head very similar to a finishing nail. The rivet is put into a special gun that grabs the top of the nail. The rivet is then inserted into a hole drilled in the two pieces to be joined. Squeezing the trigger pulls the nail through the hollow rivet, expanding it and squeezing the two pieces to be joined together. Since the expanded portion is only slightly larger than the rivet itself, if a backing washer is not used, any appreciable force exerted on it will pull it right through the flexibile fiberglass. Works very well on metal; almost all jetliners are at least partially assembled this way with special purpose rivets, but they are all metal. If your hull is an aluminum hull and the deck is joined to aluminum structural members, then the rivets will be sufficient for the purpose.

Since you are already intending to separate the hull and deck, replace them with 1/4 X 20 truss head stainless screws about one inch long, with a washer and self locking nut behind each one. Buy them at a franchise called Fastenal. You can also get them at swimming pool supply stores. They are usually used to assemble above ground pools. Much superior method of joining but you will need someone's help since in all probablilty your arms are too short to turn both screwdriver and wrench.

Woa with that drill.

How close is the floor to the hull, i''ve seen guys drill right thru the hull not thinking it was that close.

Thats a aluminum rivet, and the op didn't know it ?

Bond-o is right he needs some one who knows what they are doing, showing him the ropes.

Big damage can be done with a drill in the wrong hands, second worse thing on a boat that can do damage is a hammer. I keep one on onboard a little ball preen hammer. Only reason i had to use it was to tap the starter. And tap the t-stat housing to remove it.

Not wanting to start a flame war here, but that seems a bit harsh toward someone who's just getting started out and came here asking for advise. I'll bet not a single one of us were born the mechanical geniuses we are today, we all had to learn as we went (and some of us are still learning).

Gotta admit I thought the same thing,but yeah a little harsh! I just can't figure out what the heck it is doing there-doesn't look like it's doing any good except maybe holding down a loose spot of carpet? Biggims,can you just grab it with a pair of pliers and pull up on it a little-see what it does?? Is that the only one,or are there more?

Re: What is this and how do I get it out???

That rivet looks way out place, carpet riveted down lol how pethetic. Unless theres a bunch more in somewhat a symetrical pattern that were not seeing but it just looks like a rougue leftover that got trampled down into the carpet.

Re: What is this and how do I get it out???

Seems strange that they would pop rivet through the carpet to hold the floor down. I would like to see a larger overall picture of the inside of the boat. My guess, and perhaps some of the other members , feel you will need to remove or cut away the carpet, before you start to remove the decking.

Re: What is this and how do I get it out???

Thank you for all of your replys.

There are several of those rivets in a symetrical shape on the deck. I am assuming those are whats holding the deck down. I only took those two pictures to give you a closeup but I?ll get a picture of the whole deck.

The entire structure is aluminum. No fiberglass that I know of. Just aluminum and wood for the deck obviously.

There is also some plumbing under the deck for the bilge pump and livewell.

I dont really need to take the deck up at this point. Atleast I dont think. But I wanted to to become more familiar with the boat. Perhaps I should wait untill I have more experience.

The other reason I wanted to take it up this spring is because recently some water got under the deck and froze. Now again, I know next to nothing about boats but can?t frozen water expand and break seals in the hull?

Thanks for everybodys help....

Re: What is this and how do I get it out???

I wouldn't worry about freeze breaking the seals in the hull. Most aluminum boats can handle that without a problem.
Water/ice in a livewell line can break it though.

 

[Biggems]

Re: What is this and how do I get it out???

ok well I?ve never used the livewell for anything other than a storage box anyways so I?m really not too worried about that. As long as you think everything else will be ok with the ice.

What about the bilge pump?

you can't just "take up" a deck......it doesnt work that way.

agreed

this is a case where you need to understand what, .........ayuh...means in each different situation.......i didnt read it as harsh at all....but rather to save the op from hurting his boat.

this is why the forum exists......but as dj and bond-o pointed out.....it is better to learn first by reading here than to "jump in" and drill or saw thru your hull....

That rivet looks way out place, carpet riveted down lol how pethetic. Unless theres a bunch more in somewhat a symetrical pattern that were not seeing but it just looks like a rougue leftover that got trampled down into the carpet.

70.....i really dont think its "stock"....ive never seen a mfgr do that.....its a deck replacment for sure. its also done by someone that "did what he could think of" to get the job done.

ok well I?ve never used the livewell for anything other than a storage box anyways so I?m really not too worried about that. As long as you think everything else will be ok with the ice.

What about the bilge pump?

.

if i understand you correct......the internal watersystems are iced up.....that is not good......they can and will crack/split....
to properly winterize the boat....any water holding systems like this....(ie ...head...shower galley...ice well....beer cooler) must be drained or filled with antifreeze.


however....it doesnt matter what is wrong or right with your boat my friend.....there is enough talent on this forum that has been there done that to get you fixed up in no time

if you want to find out about your deck.......read the restoration forum here at i boats........then read some of the compleated projects forums.....dj did a great job on a aluminium boat....also lundwanissas tinny.

then search core sample.......

after you spend the 2 hrs to do read all of this im confident you will know and understand how easy it is and what to look for with your boat.

cheers
oops

Re: What is this and how do I get it out???

I don't think Bond-o was to harsh just think before you do.

Than think some more with a drill in your hand.

Good luck !

Re: What is this and how do I get it out???

HOLD ON THERE!!!!

Don't even think about touching that rivet!!!! ​

Everyone has seen this before. Its the last fastener put in the boat that actually holds EVERYTHING together. If you remove it, the boat will literally fall apart before your very eyes.

Are you sick and tired of fasteners that are in the wrong place? How about fasteners that hold everything together? And we all know the pain and agravation of trying to remove fasteners with the wrong tools!

Well you can kiss those problems good-bye for ever!!! Introducing the amazing Oxy-Rivet remover! It removes those pesky fasteners with the power of oxygen! Just like an oxy torch cuts through the toughest steel, this tool will remove the most stubborn fasteners and leave a clean smooth shiny surface behind.

Now if you act in the next 10 minutes, for three easy payments of $29.95, I will send you the Oxy-Rivet Remover that will be able to remove the offending rivet without causing the boat to self destruct.

Act Now!!! You'll be glad you did!!!

Re: What is this and how do I get it out???

i've looked at the northwoods boats and yes they are an entry level boat not the same quality (or perceived quality) as a lund or crestliner but don't let anyone on here put you down because it's the boat you own. it's got a decent hull design and most northwoods have a lot of extras for the price. it's a great starter boat to get out fishing and get on the water. my advise is don't worry about what is under the deck because when something starts to go bad under it you will know and then deal with it. cover it up to keep any more snow or rain out and worry about when and where the fish will be biteing when you can get it on the water.


-18 degrees this morning 30in of ice on the lake and the fish have been biteing. could it get any better!

I THINK SO...

76f, mild southerly winds on Saturday produced agreat day of fishing in the warm Gulf waters (66 degrees). Produced some grouper and three octopuss...sorry, didn't mean to hijack this thread....
