This SEI-206 gearcase is for a 20" Transom Motor. It is in excellent condition. Fresh Water use, no nicks in casting, bends, cracks, etc. Paint scuffs from a transom saver is the only thing that stands out on the gearcase for cosmetic wear. Shafts in Excellent shape as well. If I had to guess it looks like it was used 1-2 Michigan boating seasons. Drained for shipping, vacuum and pressure tested with zero drop.
Impeller was not checked, suggest replacement before installation. Lower unit MUST BE FILLED WITH PROPER GEAR OIL FROM THE BOTTOM UP BEFORE USE.
