Oh wow, they certainly made some changes to the manual! Thanks! So, they've extended the oil change interval from 100 hours to 200 hours. Does that seem reasonable? I wonder what that decision was based on? Was the 100 recommendation a typo in the old manual, or is 200 a typo in the new manual? I can't imagine that Universal's understanding of oil breakdown has changed that drastically... Now I'm curious what is recommended for most similar marine engines of other makes or models.
