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.
That would be the bell housing, and to remove it you remove the two hinge pins it swivels on. One is barely visible in your picture. Then you will need to remove the bellows and shift cable to get it the rest of the way off.
The bellows and shift boot are glued on using bellows adhesive, weather-strip adhesive, contact cement,etc.the only one not glued is the exaust bellow.
