Bilge install question

[jorgeinmiami]

I purchsed the 2 bilge pumps and I have a question on how fix them to the bottom.

It looks like they have places for screwing them down but do I first have to glass in a piece of wood to the bottom?

or would a amble amount of 5200 get the job done?

best way suggestions please!!!

I also purchased some other goodies !!
