Yeah, I think what I took away from this whole L/U experience is that the smallest deviation can throw off the linkage. There are just so many darn moving parts in an outboard motor, it's amazing they don't break down all the time. I suppose that's why they're so expensive.
Oh, by the way, a big thumbs up to a guy who goes by the handle of HPBB on this forum. He sold me the lower unit at a very fair price, shipped it when he said he would, and answered a lot of my questions. He could have chose to stick it to me on the price because there's not that many L/U's like mine out there, but he didn't. There's still good people out there. Thanks Jim.
