Painting a outboard (touch-up)

My '98 Honda has some paint that has flaked off that needs touch-up. It's the plastic area below the cowling - about 2-3" high. I have some Honda touch-up paint, but the can doesn't really have any directions. Is there any special prep I need to do to the plastic (other than clean it up)? It's pretty slick, so I'm pondering giving it a light sanding.
The second picture here shows it pretty well.
Anyone have any tips?
Thanks in advance,

Wet sand the transition from good paint to bad, up to at least 400 grit. Make sure there is a smooth, feathered transition. Wash with water, degrease with mineral spirits or acetone, then mask and paint. Make sure temps are 65-75 F, reasonably low humidity (no rain in forecast) and no wind or the overspray will be all over the place. Use 2-3 thin coats, and don't put the paint on too wet (by spraying close and/or moving the can too slowly) or too dry (spraying too far away). It should go on with a nice wet shine, but not sag or run. Also, most paints require recoat within 2-4 hours or else wait at least a week for a full cure. I have found the factory branded paints to be worth the extra cost over the generics. I just used some Mercury touch up and was really impressed with how well it went on, and how much gloss the finished job had.

For advice on how to re-paint an outboard lower unit, I suggest this article:

yeah, I saw that Jim. I'm not dealing with the lower unit on this project - at least not yet :)

I have same problem on '87 Johnson except area affected is more advanced than yours. Andygere's advice sounds good to me except that I would need to pick off a lot of loose edges before sanding. At least you got more responses than my post did.
Seems odd that you and I are only ones with this prob. Maybe it's the '87 Montauks that the engines are mounted on

That's probably it Gene :)
I too have some loose paint at the edges to pick off....it doesnt' seem to stick well to that rather slick plastic. If you want I'll give it a shot and email you with results. Let me know.

In reference to:
It looks like you need to re-paint the midsection of the engine. I can't believe that is plastic. I would think the same sort of preparation and painting technique would be applicable as I described.
Are you sure that midsection is plastic?

I'm positive Jim...plastic....damn cheap Hondas :)

'87 Johnson 90 sure looks plastic. Maybe it's like the duck. It's not metal, it's not fiberglass, so it must be plastic. At least it doesn't corrode or rust.

Primer is usually used to prep the area the paint is going to cover. I use Tempo brands.
