C-M, The LU are a bit tricky for backyard mechanics. Reverse is a bit of an odd gear to be stuck in. Does the LU have gear oil? Will the shift shaft turn at all? The only way to disassemble the LU is to pull the donut shaped retainer (behind the prop), and pull the bearing carrier, with a puller.

I had a go at pulling my lower unit down a few's weeks ago. Let me asure you it was not a fun exercise! My motor has seen a lot of salt water over the years which made the carrier seize to housing. the rest of it come apart fairly easy though..
