Power trim clicks

I have a 50 hp 4 stroke(62y F50TLRY) a few months ago I had the trim motor replaced and it worked fine now for some reason it began clicking when I trim it up.It doesn't do it all the time it just clickes but it will go down all the time.Can you tell me the part and number that I can order Thanks
