:twisted: Possibly bad water pump. Do not use it until you find out the problem otherwise you can cause severe damage.

Check "pee hole" and intakes for obstructions (mud). Blow them out with air or clean with a pipe cleaner. Crank up on the water hose for a few seconds to see if it pees.
If not, Pull the lower unit & check the water pump. If shot, replace.
If good, check the thermostat and make sure it is not stuck.

If the engine got hot then it is more than likely the water pump. However depending on how hot it got the damage may already be done.

are they hard to replace? how much are they?

Just a few bucks. Unlike a car, which has an external water pump that must be replaced whole, the outboard water pump is in the top of the gearcase, and comes apart, allowing you to replace the only part that really ever dies - the rubber impeller. Fairly simple job too. Go ahead and pull it, and it should be pretty evident as to whether it is the problem or not.
