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.
Success...kind of. So if this is useful to anyone else, removing the two bolts on the motor end and the allen bolt closest to the motor allowed me to get this far. Ill try to post update if I get this thing fixed.
The motor seems to test ok. Equal resistance across the commutator and side to side and no continuity between the commutator bar and the armature stack. Also it turns freely by hand within the unit so that's a plus. Next step is trying to source some new bushes.
