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.
You can use either the Champion QL77JC4 or the L77JC4 plug, gapped at .040 .<br /><br />The "Q" indicates a suppressor plug, used to help quiet interference that might affect any installed electronic equipment.
