    Pro Xs 115 Lower unit oil change

    I’m looking to change out my lower unit oil as the season is about over. Should I replace any of the seals while I am draining and refilling my lower unit oil? If so does anyone have any part numbers on what I should get? Also will a standard pump fit on the lower unit? I noticed I have to remove the prop to get to one of the drain screws and fill from there.

    Motor s/n is 2b621928

    You will need two (2) 830749 Drain/Vent plug seals, and one quart of Mercury or Quicksilver High-Performance Lube.

    Uses the same pump that has been utilized for previous models.

    Note: Moving your thread to the 4-stroke forum for you.
