Seadoo 3d 2005 maintenance help

[Will1]

I have two seadoo 3ds from 2005 which have only been used a few times when first bought and have been sat for about 10 years since, before being left to sit fuel was drained and the spark plugs were removed. Does anybody know if it’s safe to just try start or is there anything I need to do first regarding the pumps etc as they might be seized,
Thanks
Will
