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?
I guess I'm going to look into isolating the boat electrically.
Sigh,

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

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 Regards Richard Piller

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

That looks awful.
I use a galvanic isolator on my AC circuit and

There is a small zinc on the line cutter,

I am very sorry for the condition of your

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

I guess I'm going to look into isolating the boat electrically.

Hi Kent,
I cannot even imagine the problems and expense of changing the
propshaft. The pic that you have shown us looks horrendous but hopefully that is
the whole extent of the damage and if so the reduction in strength should
perhaps be relatively unimportant. Just in case the damage is more extensive I
suggest that you have someone put the engine in gear and turn it over by hand
using a lever between the bolt heads on the pulley for the fan belt and listen
to find out if the bearings/gears in the unit have seized up. This is unlikely
as presumably the engine was used recently to get the boat ashore.
If you examine the wearing out bush you will find that there
is an O ring inside it and this is what keeps the oil in whilst the bush turns
with the prop shaft and the three oil seals on the outside of the bush keep the
oil in when the shaft and bush is turning. Now you need to give the shaft a
‘colonoscopy’ to see how far the shaft is damaged. Car part vendors sell an
endoscope that is small enough to fit down the dip stick tube for about €80
euros and this should do the job. If you are unlucky and the shaft is pitted
further in than the existing O ring position look further on and you may find
that there are positions where an O ring could make a seal and if so then when
you get a new bush you can have a new
groove cut for a second O ring to do the job. If you sleeve
the old wearing out bush as I have done on mine your shaft problem may be
solved without even getting a new bush.
There is clearly an electrolysis problem either arising from
your boat or the marina,neighbours and this must be resolved. You certainly need
to get a really good marine electrician to check your wiring and to install a
galvanic isolator.
I look forward to hearing the result of your endoscopy
examination! Meanwhile I suggest that you get a copy of Nigel Calders book on
boat maintenance, It should become your bible.
Now I must go down to the yard to remove my prop (with
trembling hands).

Hi John. Maybe the pic doesn't do the damage justice. I estimate a good third of the shaft diameter is gone with similar corrosion on most of the circumference. The pitting is confined to the area under the wearing ring aft of its inner Oring. There is discoloration of the shaft for another inch or so forward of that Oring.
There was no problem motoring from Brunswick to Amelia Island and the shaft turns freely.

galvanic isolator.
I look forward to hearing the result of your endoscopy
examination! Meanwhile I suggest that you get a copy of Nigel Calders book on
boat maintenance, It should become your bible.
Now I must go down to the yard to remove my prop (with
trembling hands).

Yeah, looked there too.
Kent,
If I recall
correctly, it is not in the books with all the manuals it is (I believe) in
the owners manual with all the colored photos.
Sorry—but I
am not on the boat.

I looked through everything I have , Eric. I would swear
I've seen that drawing, but I can't find it.
Kent, In
the back of the owners manual there are pages that fold out with plumbing
diagrams, etc and also drawings of the bow thruster, sail drive and many
other drawings.
Do you have
an owners manual?

I don't have it aboard, Eric. If anyone had it I'd
appreciate it if you'd email me a copy . Karkauai at yahoo dot
com.
Kent,
I just
looked for a drawing of the C drive. It must be in the books on
Kimberlite.
From
memory I believe it will be a big job.
Sorry,
Eric
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?
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?
I guess
I'm going to look into isolating the boat
electrically.
Sigh,
