Re: removing lower gear case from merc 120
If it's stuck, it may be due to salt corrosion on the studs going through the front and the four on the sides. <br /><br />It's easier to remover the whole drive, and then fight the halves apart. You will probably have to heat the areas around the studs, and pry on the seam with screw divers. Try driving a screw driver in the seam at the very rear of the drive. <br /><br />you may have to heat a lot. Sometimes even heating, then driving in screwdrivers, and then letting the whole thing cool and contract.<br /><br />It can be a pain if the drive hasn't been separated in a long time.<br /><br />I do my impeller every other year, so I don't usually have any problem splitting the halves.<br /><br />Scott.
