Im just fininshing up my winter project (98 sportster 1800) and was hooking up the battery to check to see if everything electrical was working (boat has been sitting for 5 years) and found that everything works but the bilge fan seems quite loud. are they supose to be really loud and clunky sounding? I ran it for 5 min straight and it still works it just seems loud and like its going to come out of there. if anyone has a spec amp draw rating on that fan that would be great too.
