aluminum boat repair

Question

uffdapete

Anybody have good suggestions for repairing a 25 yr. old 16' Lund that leaks around the rivets? Welding I'm told is not an option on aged alum. Any recommendations about re-riveting and who can do that reasonably? There must be some space age repair stuff out there somewhere that would work too.
Thanks for suggestions!

Surface Tension

Buck them back up. Have someone with a heavy steel object hold it tight on the head of rivet. On the inside of the boat hit the rivet with a ballpeen (SP) hammer or air hammer till it's drawn up and tight. If the hole is wore bigger and wont seal center punch the rivet a drill it out. Replace with a bigger rivet. Most fastener shops will have aluminum rivet's.

Somebody in one of the forums mentioned they used the rhino lining (the one in a can) to seal up their boat they had for sale. Don't know if it would last forever, but if more than a few rivets leak, could be quicker than fixing every rivet.

The best repair would be to drill out and replace the leaking rivet(s). Solid rivets must be installed from "both sides" of the metal being riveted. But in you're boat, you might not be able to easily do this unless the leaking rivet is exposed on the inside. Seats, boat floor, etc. might make it difficult or impractical. For those situations, you can buy closed end pop rivet. (The one's found in building centers are open end rivets, and would leak) While not as strong as a solid rivet, you could compensate by gettting one size larger, and if were only a few, that would help on the leaking. Rivets are available at commercial fastener stores. Riveting instructions can be found on the web site of rivet manufacturers. Good luck.

Having your boat professionally re-riveted will cost you about $500. A buddy of mine had his 16 fter done a couple years ago. If it is an older boat you might be dealing with stress cracks as well so they will have to weld those. His boat was a 61' Lund and they had no trouble welding it.
I was the one who did the inside of the boat with Herculiner. It really worked well. If you need more info or have questions feel free to email me.
Good Luck

Here's the results of the aluminum boat repair project.

I tried silicone when I first got the boat 3 years ago, cause I've had success using a good grade of silicone on several different applications. Didn't stop the leaks on the boat very well though - maybe I wasn't thorough enough - there's a lot of rivets in a 16' Lund! Also it was a pain to clean up before the final solution described below.

I was advised by a professional welder who learned his trade in the Navy and worked in shipyards not to try welding 25 year old aluminum. He said it might work but it's risky due to some type of chemical (oxidation?) process that tends to weaken old aluminum if it's heated. I'm not a chemist or a welder, so I just took his word for it.

The boat isn't worth $500 to me, so reriveting wasn't an option.

Next option was Herculiner. Thanks for the replies and ideas on this one. After talking to Gull Guide in person, I decided this was the way to go. I bought one gallon
followed the preparation and application directions to a T. According to the instructions however it should have required 2 gallons. I decided to start with one and see how that worked. I coated all the seams thoroughly the first time and then did the entire floor 2 more times with one gallon and still have close to a quart left.
It doesn't leak a drop.

Wal Mart has a similar product by Dupli-Color for $20 less, but I'd probably spend the extra $20 cause I know how well Herculiner worked.

Again thanks for the ideas.

Ok i have heard about the herculiner deal. But now here is my question. We have a older starcraft aluminum boat. The only problem is there is a floor that runs the whole distance of the boat. Can u put the herculiner on the bottom of the boat? Or would you recommend taking up the floor and then applying the herculiner?

here's what ya do on the bottom side, filp the boat over clean the bottom with rubbing alchohol and brush on two coats of KOOL-SEAL, it is sold at any Mearnds store for fixing metal roofs. I've have to redue my duck boat about every five years, but I bust a lot of ice with it.
good luck
PS it come in a few colors and a good paint shop can match it to your boat or whatever.

Born 2 Fish -

Herculiner leaves a rough finish, so if you were to use it, I would take up the floor. What I used was also black so I put in a floor so it wouldn't be so hot in the summer and for the flat walking area.

Sounds like Phil's idea is a good alternative for doing the outside.

      Time to get the yak ready. Might need to paddle a couple spots on the sippi soon.

      Eyeguy and I made it out one last time yesterday. Access points are getting pretty bad in our area. Was finding roughly 2ft of  very chunky ice in the places we drilled holes. With the warm weather and bright sunahine we had, I'm guessing we lost a few inches through the day Fishing wasn't exactly fast and furious, we did get our fish... but really had to work for the quality.  The area we ended up finding our fish was a shallow 6-10ft dark bottom flat, close to where they will move come ice out.   It soon became apparent the fish we were targeting were almost swiming with their back right against the bottom of the ice, infact my two best crappies hit while my bait was only inches below my hole.  Baits we found better success with were the Northland slugbug and The Impulse Mayflies in bright colors. Jig size didn't seem to matter much due to the depth we were fishing. As I am typing this, my thoughts are already turning toward warmer days spent chasing smallies on the river. The boat and yak are soon to be ready, rods will be strung and so on. It was one heck of a long winter.... fished with some real good people from this site I had more good days than bad, got some monster fish locally... for these things I'm truly blesaed.... like I said,It's been a long winter....I'm glad it's over Pic is of my last big ice crappie for the season

      I will certainly keep you informed about the progress of the hatchery. I expect to see the nets and traps go in within the next two to three days. The run should be very strong as the fish are already moving into Pike Bay strongly. Cliff
    • Bigfatbert
      Thanks Cliff for your Pike River deteriorating ice reports and pics . I. Really want to show my wife the hatchery when the action is really happening this year , I would assume you will be right on that when this happens , is there any way that you can give a shout out on here as to just when this scenario is happening up there . With the warmer temps being quite steady now , I would think the run will be rather strong this year when things get going ..

      I got the 4 smaller ones the other day. They are a little over 2" long and paid only $6.64 total to my door.  The quality seem pretty good, we shall see once I put them to some use!

      Thanks Leech! Ya you need a life jacket in a kayak. I have mine behind my seat, but Yes I should be wearing it.
