Yep, this manual will help you out with timing belt replacement on your model.
It covers a wide range of Mercury 4-stroke models from 2.5hp all the way to 350hp, and the 90HP EFI 4-stroke from 2006 is right in that range. It includes detailed procedures for timing belt inspection, removal, installation, and proper alignment — plus torque specs and diagrams so you don’t mess anything up.
If you're planning on tackling that job yourself, this manual's definitely a solid backup to have in your corner.
