F100 Water pump

[roboterobote]

Newbie to this forum. I have a 2002 F100 TLRA. It was stored from September to yesterday. All worked great last year, yesterday no water coming from pee hole and temp alarm sounded. Checked the pee hole and its clear. Forced water through the hose connection and water comes out pee hole. I'm assuming the impeller is stuck/bad of there is a blockage somewhere? I'm very handy with a wrench but haven't done much with outboards. Is there a ready source for diagramatics for water pump assembly without purchasing repair manual? Reading the threads here it sounds like an easy job but I'd like a little more knowledge going into it. Any other suggestions? Thanks for any help!
