Re: Lower unit lube?
they now have a pump for installing the lower fluid, you fill from the bottom hole until it comes up to the top hole, this is make sure there are no air pockets, then install the top plug, remove hose, and install bottom plug. there are suppose to be sealing washer on these plugs, you can get them at a dealer. the lower lube is dark, and has a nasty distinct smell. the main thing to be concerned about i metal chips, small shaving are normal, chips or chunks are not.
