Default Hull Repair Question

Hey Everyone - New to the Forum, but have been lurking for a few years. Love the site!

Got a question for the experts. I'm test driving a friend's Scout that he is thinking about selling. The previous owner attempted a gelcoat repair that looks to be a crappy job. However, after test driving it yesterday and upon closer inspection today, I noticed a few small cracks in the old repair with moisture coming out. You can see the water stains where it had leaked previously.

I'm worried about the fiberglass being wet or cracked and I know I wont be able to tell for sure until I grind all of that out.

I've done some minor gelcoat and fiberglass repair before, but never fixed an old repair. Does this look like something serious, or can it be fixed by myself or professional help??
I dont want to purchase a major problem - with this exception, the boat is in pristine shape, motor has low hours and everything works on the boat.

Thanks for the help! Looking forward to being a member here.

That really doesn't look good. First it's a horrible repair, but that's not a problem if you are going to redo it. The much bigger issue is that it looks to be quite a serious crack over a fairly large piece of hull: the repair has cracked because the damage was just covered up and not actually fixed properly. To do that you're looking at a substantial job requiring access to both sides. Honestly, I would walk even if really cheap - that boat has been abused.

That looks like Marine Tex to me which is rarely a good plan and the fact that the water is colored that's coming out raises more concerns. Does Scout core their bottoms?
A proper repair is necessary and I couldn't possibly suggest what the repair will entail without first grinding to find out what the extent of the damage is.

He’ll have a hard time selling it looking llike it does. So ask him if you can grind it out. If it’s too much to deal with, It won’t be difficult at all to make that patch better than it currently is at the moment. It’s needs to be ground out and then someone could walk you through the repair.

I personally wouldn’t “walk away” because of this. There are a lot of folks on here that freak the hell out over what essentially some fiberglass and resin.

First would be to fine sand the whole of the mess off back to the original gel coat surface then find the damaged gouges id say There some serious scratch's along the bottom !!
The brown is possible water leaking out of the rotten wood where the stringers are !! if one side is wet the other side will be the same !!
So thats something else to be concerned with INSIDE THE HULL!! Stringer replacement and when you get to the transom are there any cracks and stress marks and When you take the drain pug out get a wire coat hanger and use the hooked end and poke around into the transom core looking for wet soft soggy wood and even rotten wood !
DO you want to go further ??

What size / model Scout is it? My Dorado 185 has a foam core between the outer hull and inner liner. The stringers are also foam cored and integrated into the deck/hull. There is no wood in my boat, and I believe that is one of Scouts marketing campaign items. When I replaced the thru hulls, the transom was definitely foam board, and from using one of the Bluetooth inspection cameras, there is definitely foam core in the sides, and from removing the fuel tank, there is definitely foam core in the bottom.

That looks like he hit something, broke through the hull surface, and slapped on some 5200 to fix it. I think you can be sure it is cracked.

Do you like worms ??
Because you sure as hell going to find plenty If you waste your money buying that thing !!
The scratchs are a good indication its gouged a long hole from running into and over a rock maybe so who knows if there any glass delamination in that particular area as well !
Simple answer is smile and WALK AWAY !!

I thought the same thing. Marine tex works for small cosmetic patching, but NEVER for permanent underwater hull repairs! I also worry about the color of the leaking water. It looks like "iced tea" stains from some sort of wood source. Surely hope it does not have a cored bottom!

This hull is probably much worse off than you know. Please don't exchange money for the boat unless you can sell the motor and make a profit.

If you want to investigate further see if you can use a moisture meter (has to be above freezing - hull thawed) and see how far the moisture has traveled away from the damaged area. Is it a cored laminate hull? If yes, then water intrusion could make that a very large upside-down repair. If it is not cored I would still try a moisture check but also tap around the area to see if there is delamination. The handle of a screwdriver or a phenolic hammer work well. Hear the difference between 'tap' and 'thunk'. 'Thunk' is bad.

If it seems like a small repair it will still require glassing upside down and then proper gelcoat finish work. More finicky if you will not be bottom painting.

If you love it and love a project then look closer at this. Otherwise it may be a good one to pass on.
