Hey everyone,

I have the opportunity to buy a 26' aluminum boat that sunk in a marina. It was underwater for approximately 12hrs. Are there any concerns that I should be aware of? The boat is completely painted and I'm wondering if the saltwater that got into the cavities would end up causing the paint to pit on the exterior. I understand that all of the switches and binnacles are probably toast. I'm thinking that the wiring will still be fine but I may have to trim the tips to expose new copper. The boat is similar to the photo that I've attached.

Thanks for the input,

WW

Assuming is sank in salt water, go sink it in fresh water. The solution to pollution is dilution. I don't know for a fact but if the salt water is diluted the electrolytes should be less of a concern.

IMO you can generally bet that all the electrical including the wire itself is toast. Any water that got into the wire will keep on corroding it for a long time. If you don't replace it you may well be chasing electrical gremlins for the life of the boat.

Only thing of value is the hull. Treat everything else as potential probably garbage. Although you could make money parting out the motors assuming it was not running when it sank.

I should be able to get the hull for approximately $35,000 CDN. I never thought that salt would soak into the sheath of the wire itself, but running new wire is easy enough so I'll go that route. I was going to strip it down completely and spray warm fresh water everywhere to dilute any salt residue left over.

Unless you enjoy throwing money away buy a new boat or a well maintained used boat.

I’d look at low blue book value, then add up what everything would cost to replace new plus labor when finished. Then decide if it’s realistic.

New the boat (hull and rigging) cost $105,000. That is $75,000. Even if I scrap every single last component, there is NO WAY that it would cost nearly that to rewire and replace components. I know that its a lot of work but in the end I think that I'll still be way ahead. The hull us under a year old.

Wireing is a bitch but if you want to spend the time and money you can do it. Just make sure that your using the correct gage and color code and lable EVERYTHING

Use a product like SaltAway as you open everything up. Then a freshwater rinse. As was mentioned before, the saltwater will have wicked into the wiring so replace it all. Upholstery should be good enough to not have to replace it at this time.
Dual helm? Hydraulics or cable?
If the motors come with it, they should have some salvage value. Electronics will be garbage but powerheads and lower units should work. Talk with a local mechanic about it. Then replace them with new.
You can definitely upgrade the heck out your electronics for the same price of a basic package out of a dealer. Learn all you can about marine wiring from some of the guys here at BD - some of these guys are DAMNED GOOD!
You'll be saving $10s of thousands over a new boat so remember that when you get depressed from time to time thinking "its taking soooooo long". :D

I'm thinking radar and a tower would look good, too. :)

Why did it sink?
Figure new motors. So what does that cost Up there? Guessing around $35k so that brings you upto $70k. Figure your should be able to rewire the Boat for around $3k including all fixtures before electronics.

I wouldn’t worry about the paint. Salt water would eventually get into every crack and crevice anyways.

The boat had a small leak that over the course of time killed the bilge battery. Do you all think that the hydraulic lines would be okay? It had twin G2's on it. New 200HO's installed up in Canada are about $45,000 with two helms. Good call on the salt away, I never thought of that...

The water finds anything unsealed and gets pushed under the insulation. Once saltwater is driven in there it doesn't rinse out. Tinned wire certainly fairs much better than non-tinned but for the cost (especially DIY) it is not worth the chance of issues down the road. I have seen non-tinned wire so corroded down even 10-12 feet from the end that it was stiff as a solid rod.

If your really really lucky the boat was well rinsed when they pulled it but certainly assume it wasn't. Not a fan of pressure washers but saltaway and lots of warm water rinsing is the place to start.

Personally, I don't see enough return for investment, don't forget about the entire fuel system. You might see a 20k savings over new if you do it all yourself, I've seen used ones for less than the 90k your going to be into it. JMO
