Insert one end your pump into the quart of lower unit oil
, and then screw the other end where the fitting is into the very bottom drain screw hole near the fin (part #41B), and begin
pumping oil into the unit until it just starts to come out of the upper drain screw (part #41A).
When it just
starts to come out of the upper drain screw (part #41A), remove the pump from the lower drain plug and re-insert the drain
screw and new gasket. Use some grease or gasket compound on the drain screw gasket.
Next, insert your pump into
the upper drain screw hole (part #41A) and continue filling the outdrive with oil until it reaches the very top dipstick (part
#51). Re-insert the drain screw into the drain hole (part #41A) and apply some grease onto the screw’s gasket.
*After running the sterndrive for 2 – 3 minutes at idle speed, allow 10 – 20 minutes for oil to settle, then
re-check the oil level with the dipstick.
