I am thinking to go ahead and change my 2003 205v with RTP over to synthetic when I winterize, any thing I need to consider? What brand/weight?

Whatever brand you like just make sure it meets api certification and correct viscosity for your engine.

I just did the same thing. I have been running synthetic in all my cars and get well over 250k. It's gotta extend the life of theses marine engines too.
