Re: Removing painted letters
Oven cleaner works well. Mask the area with a plastic sheet below the letter so the old paint can flow off without running down the rest of the transom.
Don't be surprised to find that the gelcoat below the old name is factory new while the rest of the hull has slightly yellowed with time.
