No Torco, break drive in with regular Mercury gear lube, 1hr idle in gear, 1 hr at 1200rpm, then 4 to 6 hrs at 3k and under then I run the Neo Oil, haven't blown a drive since I started with the SCX-4 and using John Pfahl the Bravo Shop's oil, hads down the best oil I have ever used, IMCO said the gears looked polished, drive had 2 and a half seasons on it with zero issues around 130hrs ...
