| 348.1 | Yuk squared. | CURIE::THACKERAY | Ray Thackeray MR03 DTN 297-5622 | Thu Apr 27 1989 09:49 | 19 |
| I have the same problem; even though the outdrive was painted (by
the way, with copper-based paint. My dockmaster told me it was OK
but since I've found out otherwise, but no visible damage, as afr
as I can see), I still had a lot of barnacles etc. especially in
the "tricky" bits, under the drive, in the crevaces, etc......
Anyway, I'm using a wire brush and sandpaper to remove all the old
stuff and layer of paint and am going to touch it up with outdrive
paint (don't know what to buy, yet), then paint it with some special
antifouling paint (don't know what that should be, either).
The Volvo outdrive instruction manual is next to useless; it doesn't
specify anything.
Helpers? Recommendations?
Tally-ho,
Ray

| 348.2 | Wanta be scared?? | SALEM::KLOTZ | | Fri Apr 28 1989 10:44 | 38 |
| A thought --
If you have visible barnacle growth on the OUTSIDE of your stern
drive -- have you considered the possibility of what is on the
INTERIOR (cooling pipes. etc...)
I have heard of build up that eventualy catches folks by suprise
when things over heat,...
The scary thing is this happens even to those who carefully
paint their drives (ya can't paint the insides.
Second hand solution? --
I have never had the problem so have not tried this; but, have
long time boating friend who swears by it & has been doing it
on the same boat for about 8 years with no negative results.
(He is in a very high barnacle growth area)
About once (twice?) a month he lifts his drive (boat in water)
gets out on the swim platform, & slips a heavy duty plastic
trash bag over the drive, then lowers the drive.
He then insures the bag is full of water and proceeds to add
a few cups of Clorox Bleach to the bag, lets it sit for a few
hours & then removes the bag. (Dispose of properly).
This will by no means remove any growth; but, he never has any
growth we he hauls his boat.
Again -- I have not tried this so I can't say if there are any
negative aspects (eating rubber, etc..) I just know my friend
seems to have good luck & others around him have picked up the
procedure.
Take care,
Lou "Phanta Sea"

| 348.3 | Try a high pressure water jet! | BIZNIS::CADMUS | | Wed May 10 1989 15:06 | 47 |

I had this problem when I hauled my boat last year, even though I used
tin- based paint. The Bottom paint on my 22' I/O had built up and was
starting to flake off after 16 yrs.
Solution was to rent a high pressure sprayer from my locla Taylor
rental . This monster cost me $70 ( 1 day minimum rent), and was
powered by a 10 hp engine. It puts out a stream of water about the
diameter of a pencil lead at about 3500-4000 psi.
I tested it on some wood before trying it on the boat- it will
definetly do serious damage to bare wood- like you wouldn't believe.
The force vcan be controlled by distance or changin nozzles. This
thing took the barnacles and ALL the loose old paint off the outdrive.
It took about 90% of the old bottom paint off without damaging the
fibreglass. What is left is going to take some serious work with a
sander or paint remover. I was careful aroud the rubber seal on the
outdrive as I suspect it would have cut like butter.
The whole job took me a little over an hour- should have called all my
friends and gone through a mass production.
This is a serious machine and you can do some serious injury if you
decide to sritz a finger or a foot, but does it clean a bottom. Even
took off the glued on boot topping like nothing when I slipped( ever
tried to get that stuff off ?)
I got the idea by watching a young lady at the boatyard last fall.
She was a new boter- purchased a 20' sailboat and launched it without
painting the bottom. When she hauled it at the end of the season, the
bottom was covered with aboput 3/4" of barnacles and other wildlife too
gruesome to mention. about 2hrs after she hauled it I saw all this mist
and heard a lot of noise where she had the boat hauled up. She was
using this machine to take the barnacles off! the bottom was as clean
as a whistle, but she had to wear glovesd and goggles beacuse of the
shrapnel!.
These machines come in various sizes/pressure ratings, and I opted for
positive removal.
It was expensive- but it sure made a dirty weekend ( orlonger) job
easy!

| 348.4 | Should have hosed last Fall | IAMOK::BELL | Bill dtn273-5217 @VRO | Wed May 10 1989 18:28 | 14 |
| WELL I USED AN ELECTRIC DRILL WITH A wire brush on it .
It took off quit a bit of "dem Critters" but not nearly enough.
the power hose sound s good but would have been best last fall.
I'm afraid they are really hardened onto the motor now.
Last fall my brotherinlaw Leo said to use bleach on the devils.I
did, and suppose it kill them. Leo used to own a mariner down Cape,
and will probably have ideas, so I'll have to ask him what I should
do next
Will post if I have any luck.

| 348.5 | Hydroblasting works well in the spring, too! | BIZNIS::CADMUS | | Mon Jun 19 1989 15:55 | 16 |

I used the power hose this spring- worked great getting into all those
crevices- but I used a 3500psi rig with a 10 hp engine- this size
machine is called a "hydorblaster"- and will literally peel the bark off a
tree- I have an oak in my yard that will testify to a slip of the hand.
I would use one of these machines with extreme caution- they CAN cause
some serious injury and/or propert
y damage if not used properly. I would
be very careful if I was using it in a boat yard with other people and
boats around.

| 348.6 | getting barnacles off fiberglass | TAMRC::WHITMAN | | Mon May 23 1994 13:34 | 25 |
| I screwed up.
I live on a brackish river in Ft. Myers, FL. A couple months ago I put
my fiberglass bass boat in the river & left it tied to the dock. Last
night I noticed the crustaceans growing on my hull. I pulled the boat
and took her to the local high-pressure carwash. I got most of the
bi-valves off, but I still have a nice collection of small barnacles.
They seem to scrape off okay using a putty knife. After the scraping
though I still have the circles where they had adhered to the gel-coat.
I'm planning to put the boat up on a cradle this weekend so I can get
access to the bottom and finish the scraping job. My question is
basically can I use a buffing compound (like you'd use on a car) to
finish the removal of the crap that's left on the fiberglass? I'd rather
not use sandpaper if I can get away without it.
Any success stories out there as to what I can use to polish this crud
off the bottom of my boat? I'm sick over this. I never thought I'd
get so much growth in such a short period of time. With the boat ramp
within walking distance, this is the last time the boat will be left in
the water more than a couple days...
Any suggestions would be greatly appreciated...
Thanks,
Al

| 348.7 | Have you considered painting? | GUCCI::HERB | New Personal Name coming soon! | Mon May 23 1994 14:18 | 2 |
| Why not simply paint it with anti-fouling paint? Micron CSC will hold
up pretty well under dry storage.

| 348.8 | bottom paint is an option | TAMRC::WHITMAN | | Mon May 23 1994 14:39 | 8 |
| When I first called the local marina and told them my predicament, they
suggested sandblasting the barnacles off (at the time I didn't know they'd
scrape as easily as they appear to) and then painting. Whereas this is
supposed to be a primarily fresh water boat, I'd rather not paint if I
can find an way to get my gel-coat back to where it's sdupposed to be.
If my scrape and polish method does not give a satisfactory finish,
then I'll be looking for Petit or Micron or whatever... I'm just PO'd
at myself for letting this happen...

| I used Micron ??? on my fresh water boat. (Probably pretty foolishly as
it turns out). One heavy application with a roller lasted 3 seasons.
Although initially expensive, now I think it was a good deal. If I
was to be in salt water even for short periods of time, I would use
this stuff again but my boat will never see salt water so I probably
won't paint at all.

| 348.10 | Only took 1 quart for a 24' this year | GUCCI::HERB | New Personal Name coming soon! | Tue May 24 1994 22:24 | 11 |
| I'm on my 3rd season of "touch-up" of the Micron paint and have not had
a browth problem yet. I started out paying my son $40 to paint the
bottom. Now, he does the job in 1 day (touch-up of bare hull plus 3
coats on the sides).
I use one of those Karcher pressure washers in the fall when I pull the
boat out (good stuff) and in the Spring to remove flaking bottom paint.
One of the features of Micron is that it does not lose its strengh when
stored on land. The directions just say to wash down in order to
rejuvenate.
