I recently purchased a 1984 Outrage 18 that had never been bottom painted. I need to bottom paint it since i intend to keep it in the water 6+ months of the years. My question is, when im barrier coating the bottom do i need to remove the outboard and coat underneath the motor bracket, or do i not need to do this since the motor bracket is more than snug against the transom?

Thanks.

No, leave the engine on and paint around it.

What product are you using for barrier coating and/or what is recommended?

MR, depending on the condition of your Outrage, you may find it more cost-effective to sell and get one that is already bottom painted. Older Whalers that have never seen bottom paint command a premium in the marketplace.

If you do decide to paint what you have, the paint companies such as Interlux and Pettit have really good documentation on using their products. Be sure to sand the gelcoat aggressively to get some tooth. One other suggestion is to use a distinctly different top coat color, so you can tell when it is wearing off.

interlux 2000 is a two part epoxy barrier coat and comes in gray or white as I recall. They have great customer service on the web, with tech support for any questions.

One suggestion I might make is to get an estimate from a marina somewhere. Also specify an ablative bottom paint because with that type of paint, if you have enough coats on there, you won't have to repaint the next season. As for the reason to get a marine business to do it, if there is any problem with it they will have to fix it. If you put $200 worth of paint over $300 worth of barrier coat and something goes wrong then you are stuck with replacing the materials. And the labor. One more thing, make the first coat of paint a contrasting color to the rest of it so when the first coat starts to show through you know you need to repaint.

The boat is in perfect condition and never been bottom painted. I hate to do it, but i will be leaving it in the water 7+ months of the year. She's no longer going to be a trailer queen.

MR, depending on where you are in Maine, you may be OK with a hard finish epoxy rather than an ablative paint. We have used Pettit Unepoxy for many years in Boothbay - we typically get two years per coat, although we are only in the water for 4 months tops.
