In the fall when it was winterized I changed the drive oil and filled the resevoir to the fill line. Today when I dewinterized it the resevoir was completely full, almost overflowing. What happened? Should I be worried about it?

Did you fill the drive from the bottom drain? Assuming you did fill it correctly the tank inside the boat is really just an expansion tank. It's only real purpose is to allow over flow when drive oil gets hot. There is some movement of oil back and forth to the drive. Is your drive a left hand rotation? If so it is critical that you have the drive full to the top cause the load is up toward the cap and the bearings must be wet at all times.
