As usually pronounced, there would only be two (2)syllables: re·marked (pronounced re·markt). Despite the 'ed' ending containing a vowel, the pronunciation assigns it a consonant pronunciation, hence it does not yield another syllable for the words where it is added if it is pronounced as a 't'. For words like "added", it gets a vowel sound ... add·ud (or add·ed) so it adds another syllable to those kind of words.
