apply epoxy underwater?
 

Hi, is there a repair epoxy you can apply underwater for emergency
patches? There used to be a two part product called safe zone or
something but it costs $100 for two handfuls. Has anyone actually used
it? You mixed it on deck, grabbed a handful in your rubber glove, dove
in and smeared it on? Did it work?
Thanks as always.

Marine Tex, a white epoxy putty packed in different size boxes is a good
product for this use.

Most epoxies will work underwater. I experimented with this
extensively to develop an anti-fouling compound that could be applied
underwater.

Check with Progressive Epoxy at www.epoxyproducts.com. They are good,
responsive people with an old fashioned (e.g. no glitz) informative
website. They market a wet/dry product that can be used underwater:

WET / DRY 700: UNDERWATER EPOXY PASTE
The very lastest generation of underwater epoxies, Wet Dry 700 is
Kevlar (tm) filled, underwater (or dry surface) epoxy paste. Thick but
workable at low temperatures. Use as a thick coating or repair paste,
with or without fiberglass cloth. Easy 1:1 mix ratio. Color: white.
Non-hazmat and available for export outside the USA. Can private
labeled for resale. A lot of our 1 quart kit sales are used for
fiberglass swimming pool repairs underwater. This product is about
wall mud thick. To make thicker (i.e. like bread dough) add some of
our EZ thick thickener....

There are a number of products out there. When I lost the end of one
of my prop shafts in Samoa I did some experimenting with the several
waterproof epoxies and found that Ace brand waterproof epoxy putty had
the best strength, hardness and adhesion of the lot that I could lay
my hands on when set in seawater. I used it to secure a propeller to
the shaft and it lasted until I got to New Zealand. Not bad. I've
also used Selley's Knead it Aqua underwter with okay results. All of
the products I used set up much better in air than in sea water, but
the ones that were best in the air were not the best in the water...
Cost should be less than $10 a handful, and a handful goes a long
way. I'm told that splash Zone is the gold standard in these things
but have not used it myself.

That is impressive.

What happened to the shaft?

It's a bit of a mystery to me. We spent the night hove to off Apia in
a front which may have caused the geared Gori Saildrive prop to hammer
a bit as it folded and unfolded, but in any case, when we came to the
dock the prop separated from its hub. It was a pretty decent landing
and I didn't actually notice the prop was gone until we attempted to
leave the dock, but my speculation is that it fell off when I put the
engine lightly in reverse. At any rate, the hub and hub nut were
still on the shaft at this point, but when I removed the hub nut all
but about 1/4 turn of thread came off with the nut. Why? I don't
know. The usual suspects or crevasse corrosion or improper torque
come to mind. The former seems more likely to me as I used a torque
wrench to tighten the nut the last time I'd changed the zinc, but...
It is a failure that is fairly common to Yanmar Saildrive shafts. I
put a two bladed fixed prop on with the nut pretty much held in place
with just the epoxy and good will and it held all the way to New
Zealand. For which I am very grateful and somewhat amazed as we had
the boat up to 18 knots at one point and weathered a gale along the
way.

I have a friend in Sumter, SC, who did something like that with his
airplane. He flew from Sumter, in the midlands of SC, to Greenville
Airport, NW corner of SC, in his little 2-cylinder Champ 2-seater with
the wooden prop.

As he came in on final at Greenville, he let off on the throttle and felt
the airplane "shudder", as he put it. He fed it a little power and flew
on into the airport thinking it had dirt in the tiny carb again, getting
off the busy runway short in such a short landing plane and taxied around
to the FBO to store it. About 8 people saw the little Champ taxi around
the corner of the building, stop then shut down its tiny 2-cylinder
engine.....at which point the entire wooden prop simply fell off forward
onto the ground, all its many bolts sheared right off! Bill left it with
the mechanic who talked the prop company out of a free replacement,
rather than all those lawsuits and lawyers and court costs.... The prop
company even paid the mechanic's bill.

Bill came home on Trailways, pretty shook up. The little ragwing would
have been destroyed if that prop had gotten off its mount in the air and
come back into the fabric wings.....not nice.

He's still got the plane with the replacement prop, last time I saw
him....It's only problem is you fly into an airport and noone rushes out
to put 8 gallons of avgas in its little tank behind the engine. He used
to like me flying with him because I wasn't afraid to prop it by
hand...no starter...no electric system! In a headwind, the Volkswagens
on the ground were beating us going West...hee hee.

Thank you, wow, that's $10 per ounce for the product if it's the ACE
hardware store brand. (us chain store). Fine if you only need a
smidgen but not practical for an emergency hull breach.
Glad you made it to NZ. We had a somewhat similar problem with a
folding prop that went fine in forwards but had no reverse, which made
for an exciting approach the first time we docked, which was of course
when the problem presented itself.
The owner thought the transmission was the problem but it turned out
to have a sheared lumen shaped chuck in the key way which locked the
prop to the shaft. (forget the correct term for this). Thanks again.
