+1 The thermostats can build up crud on them, just as important as replacing the impeller. I change mine every two years, sparkies every 4 years, drain and replace lower gear oil every fall. If there is water in it your lower unit can turn into a rusty anchor. Fishing line can damage the seals on the shaft...trust me.
