Marina painted boat , Plus Stern Drives , After 30 days drives loaded with Barnacles

[alan ber]

Was stored IN/ OUT ,
Moved into a wet slip ,
30 days ago , boat was painted ,
Marina used Vivid Paint by Pettit , a soft anti fouling , this way I can leave out of water on trailer not
effecting paint ,
Boat has twin Volvo Penta Stern Drives , Not a fan leaving stern drives in water but made
that decision until boat is sold ,
I was assured the Vivid Paint has no copper fine for bottom paint plus drives ,
I am in Daytona , direct hit of current storm Dorian
As mentioned I have a trailer , Yesterday I Pulled boat , taking inland
I could not believe the amount of growth after 30 days ,
Came prepared with power washer ,
Green slim on bottom of boat that came off easily
Barnacle growth on drives , all cavities behind , Bellows , all had growth ,
Duo props ( not painted ) loaded
Areas that were stainless painted had limited growth
Plastic transducers that is black in color was white with growth
Drives were painted, I was not there and don't know how they prepared barrier ??
I have a call too Pettit , need too make sure the Vivid used is fine for drives ,
Next call is too marina , Paid extra for drives ,
Those of you that have stern drives in water , what paint did you use , and how do you prepare
all areas , bellows Everything in that area ,
What do you put on stainless props ?

This is why I do 99 percent of my own work ,

Alan,

growth has nothing to do with type of paint. Barnacles will grow on any surface, painted or other that sits in the water and is not moving.

they start growing about an hour or two once the boat stops moving. that has been my experience with my boat when I over-night

the paint is there to ablate and allow the barnacles to come off a bit easier than without bottom paint, and its there to protect the hull.

Few friends of mine with sail boats in the St Pete area would pay divers once a month to scrape the barnacles off, or go down themselves with a hooka rig and scrap themselves (then itch for a few days)....and pay for yearly haul-out for re-paint

you can paint your props, i believe Ted does

you can also try vaseline (works for about 5 days) or a barnacle bag for the props, or Lanocote (lanolin and other stuff mixed together as a prop anti-foul) however barnacles do still grow on props, rudders and outdrives

Hey tpenfield how many barnacles do you get for the few months a year your in the water?

TASSIE
Apx 2 months ago I posted
ASKING , Painting a bare bottom 30 ft cruiser ,
Since it was never painted sanding & barrier coats was the tuff part , I try too do 99 percent of my own work but heeded family and others posting ,
I am glad I let them paint , When I arrived too check out 3 guys were on boat , Barrier painting
From the get go marinas painter was complaining about the work painting drives , Paying extra , I never expected the amount of growth after 30 days
My first thoughts was since painter was complaining he did shabby prep covered by paint , then my thoughts went too a poor choice of paint since NO Copper for drives , I was assured Vivid had no copper and would be fine for drives ,
Now painted I wanted too see what other options I can add such as behind drives , possibly
adding a different paint , Growth was concerning , Even if I went the diver route no way would they
get the growth between the drives , Having a trailer I can shoot it clean with a power washer monthly . Not about the money , its anal me ,

Barnacles or slime should not grow on anti-fouling paint. If you have lots and lots of barnacles, then the paint probably was not an anti-fouling paint, or a really poor brand. Vivid should be able to keep away barnacles for a season (3-4 months)

I used to use the copper ablative paints, and they worked fine. With my powerboats, I started using ePaint EP-2000 for the hull and either 'ePaint ZO' or 'Interlux Trilux 33' for the outdrives and the propellers. If it isn't painted, it will have barnacles. So, that means the bellows and transom assembly all get regular coats of outdrive anti-fouling.

My boat stays in the water (Cape Cod, MA) for 4-5 months a year. The hull may get a couple of barnacles, and the running gear may get a few. I usually let the few barnacles die over the winter and they come off cleanly in the spring during boat prep work.

One year, I went with cold galvanizing spray paint on the propellers and it kept the barnacles away, but slime grew on the props fairly quickly. Now I do an undercoating of cold galvanizing and then the outdrive anti-fouling as a top coat. It seems to work fine, although the props are not quite as efficient with paint on them, but letting barnacles grow would be a whole lot worse.

If I lived in an area where boating is year-round (FL), then I would probably pull the boat and re-paint 3 times a year (i.e. every 4 months). My experience is that most of the growth comes in the last month of the season, or after the boat has been in the water 3-4 months, as the paint is starting to loose its effectiveness.
