Is it safe to put screws in the bilge floor?

I have a bow mount trolling motor. The battery is in the central storage space between the two front fish boxes. Please see the attached pictures. Assume the green rectangle is the battery. I want to put a battery tray there and secure it on the floor. I may need to put four screws on the floor (illustrated by the four red dots in the picture). My questions are:

Is it safe to put screws there? If so, what's the maximum length of the screw? Or is there any other way to secure a heavy battery in that area?

Thanks in advance.
