Please note that the PICTURE UPLOAD function is not working. The iBoats Forum Moderators are working with the system administration folks at the parent company to get the issue resolved. This happened about a year ago and here we are again. In the meantime you can post photos as links to a picture hosting site of your choice. We are sorry about the inconvenience and will advise when the issue is resolved. Thank you for your patience.
how do I remove the cap to the black water tank? I tried banging on it with a hammer and socket driver, and a huge oil filter wrench (kind of like crab claw pliers); both started to cause damage to the teeth on this cap.
