I have a shifting issue with my outboard.... The other day I changed the oil in the lower end gear box. I proceeded to the lake and ran the boat for an hour or two without problems. I was slowing down and the engine died on me. I went to shift to neutral before re starting the engine. The engine wouldn't shift out of gear. I finally got it in to neutral and was able to start the engine. It seems that the lower end is having shifting issues. I pulled the drain plud on the lower end and found a bunch of metal shavings. I started to take the lower end off , but can't seem to be able to get the unit to seperate buta half of an inch. The diagram shows the parts but i don't see what is holding it from seperating? Anty help would be appreciated.
