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.
Re: bad history with 1980 140 V4 john (A Must Read)
Sorry about that. The RPM reading is from the factory tach assuming it is right and the speed reading is from GPS which has been very close to the mph speedo in the boat.
