Re: lower unit oil change

When you are looking at the lower unit the plug on the right is the fill hole and the one on the left is the vent hole. You fill this unit the same way you do the over and under ones. Keep insterting oil in the fill hole until it comes out the vent hole and then re seal the vent hole and then re seal the fill hole.<br /><br />There should be a drain hole on the bottom near the pivot shift pin.
