Bodø ferjekai - Moskenes ferjekai walk on, how long to show up in advance

We have a flight booked from Bergen to Bodo which lands at 3:35pm, and are trying to catch the 4:30pm ferry from Bodo to Moskenes on May 25.

Do we need to book in advance if we are just walking on?

Is this enough time to get from the airport to the ferry terminal?

How long in advance are you required to be at the ferry if you are walking on?

Thank you!
