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.
If you have a 50HP motor with an ignition system that uses points, use Champion UL81C or RL81C gaped at .030. If you have the electronic ignition, then use Champion L82C or RL82C also gaped at .030.
