I will research this question for you, I will check the archives and see do passenger records exist.
The good news is that records do exist from 1825 to 1900, the full details are in the article below.
the LDS (Mormons) have a worldwide network of libraries, you check their catalogue for a particular microfilm, you order the microfilm and they advise you when it has arrived at your local LDS library.
There is one online record that you may find usefull, civil registration records in Chile from 1885 to 1903
