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.
The parts list says:
SPARK PLUG, Ch ul-77v 3 3 ALTERNATE SPARK PLUGS FOR SPECIAL APPLICATIONS: 386143 AC-M40 FF; 386144 Champion L2G; 386145 CHAMPION L77J
The surface gap plugs are usual I think for sustained high speed operation.
