Small Outboard Rehab

I'm going to try and get a Mercury 15HP Four Stroke going after sitting outside for the past 3yrs or so. The guy who had it hasn't run it since 3 summer ago. What can I expect to have to do to get this thing running? Impeller, Plugs, ???? I'm guessing its around a 2008-ish model.

The things I would do are change impeller, change oil, plugs, carb rebuild, and replace fuel lines.  That should get her going.  If there is old gas I wouldn't even bother trying to start it, you will likely do more harm than good. You might be able to get away with just a good carb cleaning if you don't try to start it.
