Ebay has used 800 edge motors popping up frequently. Expect to tear it down and upgrade things though. Add a new PTO end bearing, new upper piston rod bearings and new rings. Naturally you will be replacing the seals, diaphragms and gaskets as well. It would also be good to drill out the oil drain hole that goes to the PTO bearings, that the factory never installed. the 04 and 05 engines with PERC and DET are similar. 03 may not have DET or PERC. 02 has no PERC, no DET and no compression release hole and are a bitch to pull start, but the parts can be interchanged to bring it up to 05 standards. There is an 02 800 edge engine on EBAY right now.
