Does anyone even answer this one anymore?

First of all, Hello everyone. Yes I'm a newb. So many questions, so little time. This is going to take awhile, so hang on.

I'm a 43yr old dad from San Francisco, CA. I'm a long time fisherman, but semi new to boating. Trying to get my 2 young boys out fishing and camping from a boat. I have a 12'er that's too small for my vision, so I decided to (what I thought was) upgrade. Lord what did I get in to?!

Those aluminum boats with the walkthrough windshield is perfect for what I do. That type of boat is abundant back east, but not here. Even if I found a deal back east, it would cost me a few grand to get it to the west coast. I found a 17' '87 Lund Tyee 5.3 w/ no motor. I figured 'perfect, a project boat'. I was thinking a little interior fix up and drop a brand new motor on it for dependabilty and BAM, good to go. Well i just found out it leaks.....BAD! I didn't want that much of a project.

I gambled on this purchase because the price was right and like I said, a rare find around here.

This is what (I think) I know about the boat. It was sitting in water for awhile, how long, I don't know. I dipped it in the water for the 1st time today. Let it sit for about 15min. Look through the port hole in the back....nothing. I'm like, YES. That changed to a NOOOO, when I pulled the plug out on the ramp. Lots of water, I'd say about 2-3gal. (in 15 min.). Drain it, dip it again, same result. It pours out for a good 30 sec. With that much, I was expecting to see a gaping hole I missed. Just dents and dings, nothing obvious.

Before I go any further with this boat I need to know some things, that aren't so easy to find. When I bought the boat I tried to research the anatomy of a small alminum boat to see how it's constructed. Lund service dept, not much help (maybe they won't return my calls because I'm not a dealer). Didn't find out much on my own either. Found this forum and read A LOT of post. Instantly started laughing like a mad man from the realiztion that my rare little treasure find is now a common nightmare.

So, I read about Gulvit, replacing all the rivets and mig welding. Many qestions here.....

1) Should I abandon ship NOW and re-sell? (with full disclosure).

2)If I do one of the fix choices, how much $ am I talking? (ballpark)

3)If I do fix, which fix is the best, most practicle and long lasting? (that was 3

4) Only 1 post I found mentioned 'Life Caulk'. Anybody else have an opinion on the stuff?

5)Boat is foam filled. If it's water logged, is it in my best interest to tear apart and re-do under-floor anyway?

6)Is this project just too big and costly.

7)Most importantly, does anyone know of a book/website that has diagrams or photos of small aluminum boat (for lack of a better word) anatomy.


The leak has been narrowed down to a bad spot. It's between Mid to front of the boat, which is the hardest to reach, because it's under so much.

I have lots of tools (not much money) and mechanical know-how, but don't know how to properly de-consrtuct my boat without doing too much damage.

Going to take the gas tank out and fill the middle channel with water tommorrow.

I'm not that attached to the boat yet, but if I do fix it, it should get me through a few years until I'm ready to upgrade.

If anyone stuck through this entire post, I apologize to you for the overload. I got limited time to make something happen. Thanks everyone.

......my head is spinning:confused:

sorry i can't be much help to you yet i'm still a novice myself. but one thing i have noticed that the experts here can do alot more to help you if you just post a few pictures. a picture truly does replace 1000 words. and who knows they may be able to tell you more news (good or bad) based on the pics that you may have overlooked.

good luck and welcome to iboats :). (and yes 3 weeks later my head is still spinning from all the info here :p -- not sure if it will ever go away )

Re: Does anyone even answer this one anymore?

2-3 gallons in 15 minutes is a pretty healthy leak. Have your crawled under the boat and checked out the hull for cracked welds or loose rivets? I'm assuming it has a livewell since it's a Tyee, have you checked the livewell plumbing; pump, hoses, thru-hull fillings, etc? You could probably block off the intake and discharge fittings for the livewell, launch the boat again and see if this resolved the leak, then troubleshoot from there.

Thanks for the replies. Sometimes it's nice just to be heard by those that can relate.

I thought about the livewell. I don't know the entire dynamics behind how livewells work (it's my 1st one). I will look into this further tomorrow. The livewell does not fill I'm guessing mainly because I never turned it on and the only place where water comes out, is where I pull the plug out, not out of the livewell port.

I did look the hull over pretty good, but I'm no expert. More info tomorrow....well today now.

Ayuh,... Put 20/ 30 gallons of water in the hull, while on the trailer,...
Then Look for the Leak,....
Don't see it,.. Angle the trailer differently,+ Look again...

Bondo has the best solution. It's much easier seeing where it's leaking out than looking for where it's leaking in. It could be something simple so don't get discouraged or rattled yet.

Re: Does anyone even answer this one anymore?

I threw a few gallons of water in my boat to see if I could spot some leaks. I wasn't expecting to find much that way but.......holy crap, I didn't have a dripper I had a stream! Turned out I had 2 pin holes in the bottom near my transom. I threw some JB Weld on there and that solved a good % of my leakines. So I guess what I'm getting at is definitely throw some water in it and see what you find.

Re: Does anyone even answer this one anymore?

Thanks to all. I will keep you posted. Kind of hard to see how some loose rivets, hair line cracks and pin holes can let in that much water that quick, but I'm going with the experience of the iboaters. I wish I had enough experience to be able to make a valid contribution to the forum. In time I guess.

Yup, the livewell tank won't fill you turn the pump on. But, once the boat is sitting in water the drain and pump hoses fill with water. If there's a cracked or loose livewell hose/fitting water will get inside the boat. Water not coming out of the drain and pump fittings while the boat is sitting on the ramp is normal as these drain almost immediately after the boat is pulled from the water,,, or as the boat is pulled from the water. (well unless you have the tank full of water)

Bondo's suggestion of filling the boat partially with water is a good one, just make sure you cover the livewell plumbing system during the process.
