With the corroded shift shaft having come up in several other posts, I suspect I have the same problem after 11 years in the salt. Questions:<br /><br />Where is the best place to inspect? I will be pulling the lower unit this winter to rebuild the water pump. Can I replace it then? Or does more have to come apart?<br /><br />What are the ramifications of leaving this alone? The shifting is as smooth as when it was new so it's not affecting me yet.
