I plan on moving the battery to the bow. The positive line will terminate at a battery switch on the transom and I need a bus bar for the negatives. The only accessories are fish finder and bilge pump. The boat stays in the water all season. None of the busbars I've seen are water proof. The Blue Seas battery switch isn't much better but does shield the terminals from direct weather. The marine busbars I'm seeing just have a surface cover to avoid contact. So it's safe to assume electrical contacts aren't effected by rain? Thanks...
