My pee hole was plugged where it comes out of motor housing. I unplugged it with wire,still won't pee. It has sat for 2 years. My question is how do I go about checking if my impeller is shot. Is it behind the prop?

Lunder... No the impeller is not behind the prop. the impeller is inside the lower unit. You will have to drop the lower unit in order to chek the impeller. It is a good idea to change anyway considering it has sat for 2 years. if you don't have a manual you should buy one.

Also, change the thermostats, service the water pump also, and take a look at the poppet valve...
