Boat Motor Questions

1. I purchased a used boat. This is my first boat. It has a 25 hp two stroke Mercury motor. When I stored the boat for the winter I forgot to ensure that all of the gas was out of it. If there was any in it, it should only be a small amount because the gas tank is seperate from the motor. What do I need to do to make sure all of the old gas is out of the motor and has not gummed it up? If it is in there what common things do I need to do to clean it out? Is there something I could use to flush the motor?
Also I did not check to see if there was any water in the motor. It sat for most of the summer after I used it, is it safe to assume then that all of the water evaporated? Where are the seals that are usually damaged by ice freezing up in the motor? I really don't think this happened but I would like to verify it.

You dont have to worry about the carbs. just get some fresh fuel
in it and hit the choke. the fresh gas will usually free up
one winters worth of gum.
If it froze the water pump is probably history.
it couldnt hurt to pull it down anyway and throw in
a fresh impeller, if only for peace of mind.
