If it makes you feel any better, look what I started with (picture 1). I'll bet this boat had 20 pounds of vinyl on it. I still have some of the "palm beach colors" with all of the turquoise under the dash (picture 2), in the engine compartment, on the drives and tabs and in the logo on the side of the boat (picture 3).
All white looks great. We have made the same decision you have. Leave it alone until we really know what we want to do.
