Re: [Amel Yacht Owners] Prop Shaft Electrolysis

Interesting Eric, I've never gotten a year from my zincs.  I may have a stray current on my boat. Will have an electrician check it out.  Would appreciate any advice on how that is done.

Kent,

My zincs last me a year and when I haul the boat annually  half of the zincs are still there.

Hi Kent I think the answers is loose power in the water if you're replacing your drinks every three months it in there there's either a big iron steel boat near you or somebody's leaking a lot of juice in the water then you should not a loser zincs every three months check with the marina call your insurance company

Thanks Eric. Yeah, it's pretty scary.  Lucky we didn't lose the prop.  I just discovered it and haven't talked to the marina yet.  I'll have to find out more about the galvanic isolator...good idea about just turning on shore power once in a while.

 

Any idea how to remove the prop shaft?

 

I'm going to have an electrician go over the boat looking for stray currents...any suggestions about that process?

Thanks

Wow !!

That looks awful.

I use a galvanic isolator on my AC circuit and also have the pedestal turned on only one day a week. So far in 3 months in the marina in the Caribbean I have used one kilowatt of electric.

There is a small zinc on the line cutter, and of course the 2 big ones on the rudder.

I am very sorry for the condition of your prop shaft. I believe there should be a drawing of your c drive in the owners manual . I believe replacing the shaft is a big project. It is also possible that a neighbor is putting AC into the water.

Did you have the marina check your AC outlet on the pedestal and the water around your boat?

I have just hauled Kristy out to repaint the bottom after 2 1/2 years.  She's been sitting in the water in a marina at Brunswick GA for the last 2 years where I've hired a diver to clean the bottom and replace the zincs as needed every 4-6 weeks.  I was surprised to see no zinc on the prop when we hauled out, and dismayed to see severe electrolytic corrosion of the prop shaft when I started changing the seals. I posted a pic at the KristySM243 folder https://groups.yahoo.com/neo/groups/amelyachtowners/photos/albums/948071197/lightbox/1877878820
I need advice on what is involved in removing the prop shaft.  Is it necessary to remove the bottom of the drive aft of the keel?

Re: [Amel Yacht Owners] Rusted Ball of Chain in the Chain Locker

karkauai
 

Hmmm. I hadn't thought of trying to cut it into pieces.  I can only get one arm and my head in there, so trying to cut it seems very awkward at best.
I think when I turned the chain around a few years ago I should have had it re galvanized then ...I left 100 ft of poorly protected chain in the locker which is rarely used.
Enough said!

Kent,

I do remember having ¼ inch of battery acid in the battery box at one time. It did no harm to the fiberglass. However that is sulphuric acid and you would be using hydrochloric.

My only thought is to get a good respirator and a fan to blow air into the anchor locker and add pounds of borax near the drain of the anchor locker and a bunch in the bilge in the engine room. Then use the hydrochloric acid.

 

Last hope is to use a cutoff grinder and cut the ball into pieces small enough to come out of the entry port. If I had this problem I would probably just cut the chain up and get a new chain.

You mean keep it off of the hull?  Afraid there's no way to do that.

The battery compartment is fiberglass, too.  It's exposed to battery acid without problems.

Not sure what to think about that.

Thanks again, all ideas are appreciated.

Surely we have a chemist on the group???

I've also discovered that the last 100ft or so of my anchor chain is rusted into a huge solid mass in the chain locker.  I've sprayed a ton of PB Blaster on it and beat it with a hammer without much success.  Right now I'm soaking it in Vinegar.

Do you have access to a tool rental shop?  You might try to find an electric "chipper".  It's a small, hand-held hammer that accepts various bits.  Often used to remove tile from counters/floors.  I know you said you have limited access but maybe you can use it with one hand and not have to do the swinging action with a mallet. Another idea is to not use your windlass to haul the chain out but use block and tackle back to your winch.  Lifting the whole mass to the top of the chain locker and then dropping it a few times might break it up.

I have just posted photos of our new security system for the companionway. As you can see the feature can be used both when leaving the boat as a extra strength to locking the companionway and when inside the boat if you want air and wish to leave the companionway open but feel you are staying in perhaps a potentially unsafe anchorage.
Arcglow in Almerimar (Spain) can be contacted by email, arcglow@..., if anyone is interested.

Problem is getting the old one out of the chain locker. It won't budge because it's all rusted together. The limited access to the locker means the fix has to be chemical rather than mechanical. Acid would probably do it but fumes from muriatic acid would every toxic. I soaked it vinegar for 24 hrs and no improvement.
Need some other suggestions.

Kent,

What about something like Boeshield RustFree Rust and Stain Remover?
Perhaps a multiple application to a specific area will give you the break
you need to get the ball small enough.

Never heard of that product Mark, but I'll see if I can find it. Soda blasting would only hot the surface, but maybe could help a bit at a time.

Re: Rusted Ball of Chain in the Chain Locker

Craig Briggs
 

   Bummer, Kent - I'd try 10 or so gallons of muriatic acid (HCl) - block off the drain first so it will pool around the chain.  Fumes can be aired with a fan as you go. 
   If that doesn't work, you could use a "multi-tool" high-speed oscillating sander with a cutting blade and cut out the bottom of one of your bow lockers about 3 or 4 inches from the side of the hull in a nice square-ish or trapezoidal shape. That will give you a big access hole and you can get a hammer on the corroded chain. 
   When you're done, you can then easily screw in some wood supports around the underside of the perimeter to hold up the cut-out piece and either glass it back in or leave it as a removable chain locker access cover - could be handy for cleaning in the future and it won't compromise any structural strength. 
  (I had to do this on my boat, not because of rusted chain, but because the unvented chain locker caused the plywood locker floor to rot out. It's really a good fix. I did have a louvered cover made for the chain locker access panel to give it fresh air and only use the solid one when we go off-shore.)
   What in the world do you think caused this?  Just age on failed galvanized chain?  Maybe a good argument for stainless chain.
Rots 'o ruck!

Hi Kent I think the answers is loose power in the water if you're replacing your drinks every three months it in there there's either a big iron steel boat near you or somebody's leaking a lot of juice in the water then you should not a loser zincs every three months check with the marina call your insurance company

I am very sorry for the condition of your prop shaft. I believe there should be a drawing of your c drive in the owners manual . I believe replacing the shaft is a big project. It is also possible that a neighbor is putting AC into the water.

Did you have the marina check your AC outlet on the pedestal and the water around your boat?

Re: [Amel Yacht Owners] Rusted Ball of Chain in the Chain Locker

Roque
 

Since you are very experienced, I take it you have already tryed the obvious solutions with no sucess. So I took a chance with less usual methods. 

Gear gun: not sure if it  will work in your particular case, but  I could once separate a few  parts "glued"  due to rust. Concentrade heat will dilate the pieces and eventuallly break a few links loose. 

Electrolysis: it envolves putting the rust part into a Electrolyte solution, using a plastic container.  
You will need a sacrifice metal and a battery. 
If you think you have enough room for this, and if everything else fails, let me know and I will try to guide you. (I will have to find a way to do this in English!)

Re: [Amel Yacht Owners] Rusted Ball of Chain in the Chain Locker

sailormon <kimberlite@...>
 

Kent,

I do remember having ¼ inch of battery acid in the battery box at one time. It did no harm to the fiberglass. However that is sulphuric acid and you would be using hydrochloric.

My only thought is to get a good respirator and a fan to blow air into the anchor locker and add pounds of borax near the drain of the anchor locker and a bunch in the bilge in the engine room. Then use the hydrochloric acid.

 

Last hope is to use a cutoff grinder and cut the ball into pieces small enough to come out of the entry port. If I had this problem I would probably just cut the chain up and get a new chain.

 

Fair Winds

Eric

You mean keep it off of the hull?  Afraid there's no way to do that.

The battery compartment is fiberglass, too.  It's exposed to battery acid without problems.

Not sure what to think about that.

Thanks again, all ideas are appreciated.

Surely we have a chemist on the group???

Subject: [Amel Yacht Owners] Rusted Ball of Chain in the Chain Locker

 

 

I've also discovered that the last 100ft or so of my anchor chain is rusted into a huge solid mass in the chain locker.  I've sprayed a ton of PB Blaster on it and beat it with a hammer without much success.  Right now I'm soaking it in Vinegar.
Any ideas?
Thanks,

You mean keep it off of the hull?  Afraid there's no way to do that.
The battery compartment is fiberglass, too.  It's exposed to battery acid without problems.
Not sure what to think about that.
Thanks again, all ideas are appreciated.
Surely we have a chemist on the group???

Re: [Amel Yacht Owners] Prop Shaft Electrolysis

Thanks Eric. Yeah, it's pretty scary.  Lucky we didn't lose the prop.  I just discovered it and haven't talked to the marina yet.  I'll have to find out more about the galvanic isolator...good idea about just turning on shore power once in a while.

Any idea how to remove the prop shaft?

I'm going to have an electrician go over the boat looking for stray currents...any suggestions about that process?
Thanks
Kent

Wow !!

That looks awful.

I use a galvanic isolator on my AC circuit and also have the pedestal turned on only one day a week. So far in 3 months in the marina in the Caribbean I have used one kilowatt of electric.

There is a small zinc on the line cutter, and of course the 2 big ones on the rudder.

I am very sorry for the condition of your prop shaft. I believe there should be a drawing of your c drive in the owners manual . I believe replacing the shaft is a big project. It is also possible that a neighbor is putting AC into the water.

Did you have the marina check your AC outlet on the pedestal and the water around your boat?

Subject: [Amel Yacht Owners] Prop Shaft Electrolysis

 

 

I have just hauled Kristy out to repaint the bottom after 2 1/2 years.  She's been sitting in the water in a marina at Brunswick GA for the last 2 years where I've hired a diver to clean the bottom and replace the zincs as needed every 4-6 weeks.  I was surprised to see no zinc on the prop when we hauled out, and dismayed to see severe electrolytic corrosion of the prop shaft when I started changing the seals. I posted a pic at the KristySM243 folder https://groups.yahoo.com/neo/groups/amelyachtowners/photos/albums/948071197/lightbox/1877878820
I need advice on what is involved in removing the prop shaft.  Is it necessary to remove the bottom of the drive aft of the keel?
I guess I'm going to look into isolating the boat electrically.
Sigh,

What does everyone think about Hydrochloric acid?  No damage to the hull?  Fumes?  How to get rid of it afterward?

Not sure what the heat gun would do???

I don't understand what you're talking about with electrolysis?

Thanks, Roque,

Never heard of that product Mark, but I'll see if I can find it.  Soda blasting would only hot the surface, but maybe could help a bit at a time.
Keep those ideas coming!
