I thought of that but the screw head doesn't seem to get to the edge of the out drive. I ll have to check again in better light. Thanks. By the way as far as the tub breaking i cut the back off all the way to the edge of the rear suspension mount. That extra area behind could give a fair amount of leverage on an area that does not have a lot of support. Trust me i stress tested it a lot last weekend and it is still ok
