I am wanting to mount an automatic bilge pump in my boat. How to I attach it? Short screws or silicone? Sure dont want to put a hole in the bottom of it. I have a manual pump now. Can I add a float switch that will make this one both manual and automatic? I think I asked that right. ThanksLast edited by kking on July 14th, 2014, 3:20 am, edited 1 time in total.
