Re: Newbie gear oil question
there is only one way to do it right, should not need topping off. if it is low, it was either not filled last time, or it has a leak, which you need new oil.
Changing lower unit oil
There are 2 straight slot screw on the starboard side of the lower unit. Top is vent plug, bottom, drain and fill plug. ( do not touch Phillips head screw).
Remove the bottom plug, put container under lower unit, now remove the vent plug, while the oil is draining, replace the seals on the plugs part # 311598, buy several of these, ( they are a one time use item)
Walmart and many places sell a little hand pump. To use to fill the unit, you insert the tube into the bottom hole, and pump till oil reaches the vent hole. Install the vent screw, then remove hose, install the drain-fill screw, clean up mess.
The screws can be hard to get out, do not mess up the head. You may need to employ an impact screw driver to break them loose.
