I have a 22 ft John boat, it's a rough riding sucker. I have 2 batteries for my troller mounted in the front of the boat, I have them secured tightly. After several attempts. Now I have a problem with the water in the battery splashing out under the caps and making a mess. Is there anyway to prevent that? I really don't want to move them to the back of the boat. Due to wire length and extra weight back there which is already an issue. I'm replacing the floor and building an extra front deck So I have options . anyways any help or ideas would be appreciated
