Is Custom 404 important for search engine optimization (SEO)?
A custom 404 page is essential for your website because it shows that you care about your visitors. Visitors who reach a ‘broken’ page in your navigation will always wonder what has gone wrong and how long the problem will last. A well-designed custom 404 page will not only solve their immediate issue but also reassure them by providing links to relevant pages in your site, or even search functionality.

One of the things Google is going to penalize after the penguin update... is multiple 404/page not found errors that you have for your site. You can test this with any keyword tool in Google. If you rank for your keyword, then in a few days, if you have page not found errors on your site's pages - these pages will stop being counted to be indexed by Google. In this case, it will result in the site completely dropping out of search results.
A 404 error page doesn't have an impact on your SEO. It is not part of the main content, it is only an information page that returns to the user. If you want to fix something in your site try placing a redirect page instead or write something on how you made a clumsy mistake.
