Title: Repairing Holes In Aluminum Boat?
Post by: Smossy on June 25, 2013, 12:31:38 PM
Ok who FINALLY got to take our 14 foot john boat out yesterday to see if it floats, It indeed does, but it has a few leaks.
They're slow leaks but even with that the second it hits the water u can see it creeping in - From a few old rivet holes, and a few old cracks that look like someone tried to patch one time and did a horrible job.

Anyone have experience with repairing/patching holes/cracks like this and what to use?
I picked up some waterweld from J-B Weld and I think Im going to give that a try, but just wanted to hear what everyone else says. The boat has lots of potential.

Loose rivets need to be replaced.  Cracks should be repaired by riveting an aluminum patch over the crack with a good sealant (such as 3M 5200) between the patch and the crack.

I am curious as well.  I have a 14 foot aluminum boat that has some cracks in the transom from too much weight or force from the engine.

Ive read that the 5200 doesnt bond to aluminum very well... Wood and fiberglass its amazing but not aluminum.. You tried it first hand?

Lots of good info in here:

See the section on Stop-drill cracks and on doublers.

5200 works fine on aluminum, I've used it many times.

Nope. I did some electric wire feed welding back in the day when I could find a job. I imagine its completely different though.

you can't weld it.



you need to install new solid aluminum rivets as stated.  You got good advice from CP.

The only thing CP didn't catch was to goop up the new rivets before you install them, probably with that same 3m stuff he mentioned.


If you lived close I'd help you buck in new rivets, it's a two person job and best left to someone who knows how to run a rivet gun.

Yeah and I have no idea what a rivet gun looks like nor how to use one. Where you located KF?
This is basicaly now a project boat and Id like to get it in good working order. Repair holes, strip and repaint, place carpeted runner boards on the floors. Maybe even install a small live well or battery box.

Leaky rivets, been there done that...........the redneck way is to drill out the old rivets and replace with nut and bolt, with a nice rubber gasket.  She ain't purdy, but she don't leak........just a helpful tip from the hillbilly section :IBCOOL:

Next question, should I just remove/uninstall all current rivet's in the boat, then redo them all? Or just repair what ones "I think" need fixing.

Post by: KFhunter on June 25, 2013, 02:41:33 PM
That's a nice little project there  :tup:


If you decide to rivet it yourself just pratice on scrap metals, just use low air pressure and a lot of trigger control on the rivet gun or you'll walk that sucker and leave a bunch of pucker smiles or flatten the rivet too much.


It isn't rocket science.   Also get you a cleco kit, almost a must have for projects like this.

Haha. Great Idea but I want it to look good also so it will hold some resale value down the road just incase. Aluminum boats seem to be real saught after these days from what I see.

oh hell no  :yike:

just see if they'll spin or wiggle,  you'll see wear marks where the head is loose and working.  drill the heads with a drill bit and pop out the rivet then re-drill the hole and replace with a slightly larger rivet.  It'll be easier to drill if you have a punch and make a divit in the top of the rivet head so your bit don't walk around.

Cool, sounds do-able. Can you rent those rivet guns at like homedepot or anything? We have an air compressor so thats covered.
What kind of psi is considered low on those things? "The rivet guns"
Title: Re: Repairing Holes In Aluminum Boat?
Post by: KFhunter on June 25, 2013, 02:49:56 PM
a cleco is just a holder nothing more really,  you put it in the drilled holes and it'll suck up the two sheets and hold them tight while you drill out the rest for patching the holes.

ROTFLMAO............"oh hell no"

You may also see a black residue around loose rivets...my experience with riveted boats, says, overpowering the boat with an outboard and beating it to death, is usually what loosens rivets. does it look like someone had an outboard on it?

Yeah, it does actually. The stern "I think" is all beat up and the top of the aluminum on the boarder is all torn like there was alot of weight on it. Going to need repaired also but It doesnt effect the way it floats. I only plan on using a 30lb thrust trolling motor.

If the existing rivets aren't too bad, just tighten them up with a rivet gun and backing bar.  Replace the bad ones with new rivets.  Might have to go to a bigger rivet on those.

After bouncing my project boat off the bottom going up the Palouse I too had a leak or two...filled the boat with water from a garden hose...any rivet leaking I circled with a sharpy and when it dried covered with JB weld...worked like a champ! the next year we went up water was a little lower...holes a little bigger...now its gonna take a welder  :chuckle:

Yeah, but then it could be used for putt putt golf! (My dad had an old Chris craft he was storing at my aunt and uncles, waiting for him to restore. They had a tavern and when they added putt putt golf to it, they included the boat)  :yike:

You just might want to look at the rivet's used in a boat! Most are peened rivets for a reason.   :dunno:
But I guess anything is worth a try once.

I just built some floor boards so I don't have to see the water and the dog doesn't have to lay in it, then got a bildge pump. Rivet boats leak. The hillybilly bolt method works too but use a pan head machine screw on the outside, poke the screw through a piece of innertube rubber add a dab of silicone and crank er down then grind the bolt flush with the backing nut on the inside and ping it. I had two rivets snap right along my keel, just stuffed some of that two part rolled stick putty, the underwater kind, in the holes. Stay'd dry for awhile, getting some more water now, but I'm one of those overpowered beating the hell out of it kind of guys. Going to have to pull the boards up again and take a look at it. Might try some of that flex seal.

That is an awesome offer, I really appreciate it!

Bucking would actually require me to find the offending rivet, LOL
I was trying to take the lazy way out.

Mine hardly leaks but would still like to seal it up well.
Maybe bucking the rivets is the smart thing to do, LOL

I used to build aluminum horse trailers and custom boats,we welded the frames and buck riveted the skin on the trailers,we also buck riveted some structural components on the sides of the jet boats so as not to wrinkle the sides.

  My old man bought a 14 foot alaskan smoker craft that got dumped off the trailer going down the road for 100 bucks.it was like new,had only been used once.I smeared sikaflex polyurethane caulking over the area where the transom met the bottom,cleaned the area real good with laquer thinner after roughing it up by hand with some 120 grit sand paper.It's been 14 years and the boat still doesn't leak.Sika flex caulking is good stuff.You can also clean/etch the aluminum with a water/muratic acid mixture,apply let foam and rinse off if you go the caulking route.
WEAR EARPLUGS if you buck rivet!And regulate your air so it don't get out of control and knock a hole in the bottom of the boat.I'd use the hard alloy rivets too,We used to use a few soft ones on the trailers but those were the only ones that would fail so we gave up on them and went to using nothing but hard ones.

What do you think it would cost to have someone who knows what they're doing fix it up for me? It doesnt need to be pretty, Its pretty beat up but its solid, just needs some TLC.

All depends really,if you take it to a shop you'll get the razzoo on shop time,but they got overhead which is where the razoo comes from,if it's a boeing guy who can't get enough riveting in during the day and he's bored you may be looking at a fishing trip with some beer.It's really not to tough of a project,I suggest throwing the plug in it and filling with enough water to get the leaks to show themselves mark around them with a sharpie,Drain flip over,make a map of what your going to fix,prep area around leakers,etch,caulk and call it macaroni.OR drill out offending leakers and buck some new rivets in.If you go to buck new ones in,drill one out and replace one at a time if you have a row,the other thing I would do is re buck a few rivets on each side of the replacement to assure snugness of the whole works.

Many years ago my buddy had a hewescraft river runner,we made the 5 hour drive to fish the cowlitz for steelhead,at some point the straps came loose and the bunks split the bottom of the boat,we launched in the dark,as the boat sat in the water waiting for light it filled up the back,We did an emergency repair at the launch with the MR heater to dry it,a pop can for a patch and JB weld.We fished the whole weekend without any events.Waiting for the cure time killed us the first day though,didn't get fishing till 9 oclock.

All depends really,if you take it to a shop you'll get the razzoo on shop time,but they got overhead which is where the razoo comes from,if it's a boeing guy who can't get enough riveting in during the day and he's bored you may be looking at a fishing trip with some beer.It's really not to tough of a project,I suggest throwing the plug in it and filling with enough water to get the leaks to show themselves mark around them with a sharpie,Drain flip over,make a map of what your going to fix,prep area around leakers,etch,caulk and call it macaroni.OR drill out offending leakers and buck some new rivets in.If you go to buck new ones in,drill one out and replace one at a time if you have a row,the other thing I would do is re buck a few rivets on each side of the replacement to assure snugness of the whole works.

Many years ago my buddy had a hewescraft river runner,we made the 5 hour drive to fish the cowlitz for steelhead,at some point the straps came loose and the bunks split the bottom of the boat,we launched in the dark,as the boat sat in the water waiting for light it filled up the back,We did an emergency repair at the launch with the MR heater to dry it,a pop can for a patch and JB weld.We fished the whole weekend without any events.Waiting for the cure time killed us the first day though,didn't get fishing till 9 oclock.
I used to build aluminum horse trailers and custom boats,we welded the frames and buck riveted the skin on the trailers,we also buck riveted some structural components on the sides of the jet boats so as not to wrinkle the sides.

  My old man bought a 14 foot alaskan smoker craft that got dumped off the trailer going down the road for 100 bucks.it was like new,had only been used once.I smeared sikaflex polyurethane caulking over the area where the transom met the bottom,cleaned the area real good with laquer thinner after roughing it up by hand with some 120 grit sand paper.It's been 14 years and the boat still doesn't leak.Sika flex caulking is good stuff.You can also clean/etch the aluminum with a water/muratic acid mixture,apply let foam and rinse off if you go the caulking route.
WEAR EARPLUGS if you buck rivet!And regulate your air so it don't get out of control and knock a hole in the bottom of the boat.I'd use the hard alloy rivets too,We used to use a few soft ones on the trailers but those were the only ones that would fail so we gave up on them and went to using nothing but hard ones.
What do you think it would cost to have someone who knows what they're doing fix it up for me? It doesnt need to be pretty, Its pretty beat up but its solid, just needs some TLC.
Something me and my girl want to use to get fishing when we want to get out on the water.
I see, all the leaks on the boat are on rivets, theyre loose and spin, There's one gash in the back that looks like someone tried to re-weld but it leaks also. Then theres a small crack under the tube the  plug goes into that leaks. Thats about it.

Get mrs smossy on the head side of the rivet with a reall big hammer,hold it tight,you get on the inside and hit the rivet with another hammer,it'll tighten up.Can you hit what your aiming at? Caulk the rest with the sikaflex and the cleaning I've described,let the caulk cure a couple days and your golden,smear it on inside and out,thin layer for more adhesion area.

So you can kinda re-set them just with some pressure? and where can u pick up that sikaflex stuff?

You could rebuck the rivets in the whole boat if you wanted to with a gun and bucking bar,re tension and then smash em some more,the last time I bought sika I got it at the lumberyard and Hardware sales,Hardware sales is a store up here in bellingham that has every gidget/gatget part/piece tools known to man.

Ok who FINALLY got to take our 14 foot john boat out yesterday to see if it floats, It indeed does, but it has a few leaks.
They're slow leaks but even with that the second it hits the water u can see it creeping in - From a few old rivet holes, and a few old cracks that look like someone tried to patch one time and did a horrible job.

Anyone have experience with repairing/patching holes/cracks like this and what to use?
I picked up some waterweld from J-B Weld and I think Im going to give that a try, but just wanted to hear what everyone else says. The boat has lots of potential.
.   JB weld works just fine did mine still perfect after 7 yrs

Temporary thread jack

Watch out for vehicle break ins at Kapowsin!

Thieves have been active at the boat ramp, you can tell by all the glass in the parking lot.

Ok guys, update. I've decided instead of re-riveting the boat. Im going to do some truss head Phillips screw - #10 24x 1/2 bolts with nylon lined nuts to fit. Locking washer in between the nut and the boat. and some 3M 5200 as a sealant dabbed around the inner of the hole and on the inside of the bolt head for a pretty solid seal, Going to re-rivet the entire boat I figure wth. While in rome. :dunno:
Going to clean the area thoroughly with some acetone and a light sanding right after I chamfer every hole..
I was thinking maybe even taking an old truck inner-tube, and cutting it into small patches and placing them on the bottom of the boat to where the bolt screws through and the bolt head sits flat on the rubber, to the aluminum. With a sealant still of course.
Also even placing Acorn nuts over the nylon nuts to help prevent from snags and such.

Going to be building a small wood platform on the front also with storage underneath, and in the back for battery storage.

What is everyone's take on this? I think It would help add some strength to the frame.

Takes pics of your process if you get the chance!

Every time I start a new project I tell myself, "do not forget the camera and document it" then I get busy, forget the camera and documenting, LOL

Go to any marine store and pick up a can of gluvit stuff works amazing. Its what they use on drift boats. I just did the bottom of my 14 ft smokercraft. I just painted it on all the seams.

*Update* Got the boat all fixed up mostly.
Drilled out all the old leaky rivets...
Replaced them with small #10 self sealing washers (Rubber on one side and metal on the other)
Simple nut and bolts size #10 also I believe, Covered in Marine G-5200 Sealant, Waited a week and took her out today for about an hour, absolutely no problems.
Found my last tiny leak is coming from behind the transom and down by the drain plug area, Looking from underneath theres a crack on it but It looks like something I can fix with more 5200.
Ill post photos at another time.
