Re: 250 Pro XS (onebadcat)
Although I would "recommend" a dealer service (simply so that you can have the Freeze Frame (Fault) History Read and checked for faults), you "could" do this yourself.
I'd recommend you obtain OEM Mercury:
-Water pump impeller and gaskets
-High Perf Gear Lube
-Fuel Filter
-2-4-C Grease
-NGK IZFR6J Spark Plugs (gap at .040")

My local dealer only has a DDT but I will get a fault history on the motor with that.
Thanks
Re: 250 Pro XS (onebadcat)
My belt broke on mine due to a loose bolt. My dealer claims they could have found this if I let them service my engine because they would have noticed too much slack and worn areas on the belt. There is no telling what a good mechanic would notice that may save you a trip in from the water being towed by a 1952 Johnson on a 14 ft flat bottom. Not easy to live down having my rig (listed below) http://www.bassboatcentral.com/smileys/Laugh.gif
