Lund Rebel 1650 Leaking

[JDusza]

Hi. I have been slowly bringing back a Rebel 1650 with a Honda 50, 4 stroke.
Good news: it was given to me as partial payment for a job.
Bad news: it was given to me as partial payment for a job.
The engine seems firm. I have gone through it and last time out it started and ran very strong. Had to do a bilge pump (full of beach sand, stuck, blown fuse), ignition safety interlock key, new stern light and fuse ... just stuff ...
Obviously, a couple more pieces of the package are the hull and the trailer.
The boat has seen salt water and does carry corrosion. For instance, on the trailer, the winch capstan was corroded and needed to be replaced. The screws that hold the trailer light lenses are corroded and have to be drilled out or the lens assembly replaced. The u bolts and shackles holding the leaf springs are corroded, unsafe. Rollers have to be replaced. Etc... It's all doable. Just have to be thorough.
With respect to the hull, it is leaking. I found corrosion (Al2O3 ?) around the main drain plug and sealed up the area with a silicon caulking product. I find that the hull is still leaking and I cannot tell from where. I was thinking about tilting the boat and trailer and slowly filling the boat until I see wet spots in the driveway. That might indicate a " hull latitude" to be investigated.
Does anyone have experience or advice with this kind of issue?
Thank you,
J

Was 'silicone caulk' specifcally marked aluminum safe, most isnt and can actually cause corrosion w the acetate in it used to aid in cure.

Hull latitude?

There are two ways to repair the leaks in the rivets. There's product called Gluvit that's made to seal hairline cracks and leaky rivets. It's a brush-on epoxy. You can find it here:

The other way is to drill out the rivets and replace them. It isn't hard to do but you'll need a couple of tools. There's a guy on youtube with a video of how to do it here:

Fill the boat with water to a certain level and don't tilt the trailer, while resting parallel to a road, driveway check if possible to get under the hull and detect any water leak. If tilting the trailer will cancel other possible water leaks spots to check around middle to bow areas.

Other alternative with a fee to pay for, take the combo to a marina, fill the boat with water to a certain level, hoist the boat with 2 slings placed under the transom and bow area and with a cleaner view of the whole hull will be much easier to detect any water leak..

Happy Boating​

@Emerger remember the host of this free forum is an online retailer, dont link competitor links.

On a aluminum riveted hull sometimes filling with water will push down on hull causing leaking rivet to seal and not leak. `My duck hunters use rhino liner to seal the inside of their old boats..gives traction and seals all leaks. If your has a interior might be better and cheaper to have bottom sprayed.

Great ideas!
As always, thank you.
