checking out my oil hubs, had the boat three months,for those of you who do self maint,there is a bottle with a pump kit at wallmart for lower unit which works very well,it also fits the hole on the hub,if you un screw the see through cap let the old oil run out, put the hose where the allen screw was and pump oil,the new oil will push the old oil out of hub,you will need something to catch old oil,pump it about four times put clear lid back on face of hub,put your hose back over the hole but do not put in,hold at a angle for air to get out,about three pumps will fill the hub back up
