05 Mercury 60 hp Bigfoot 4cyl 4 stroke. Lower Unit oil?

[Catchnemalldayy]

This is probablly a dumb question but im changing the lower unit oil and cant exactly figure out how much it holds and the exact way to fill. Ive gotten half a quart in the fill hole but it seems i drained more than this out. Please help. Thanks

get a hose & a fitting that will insert into the bottom hole of the lower unit undo the top screw and pump 90 weight oil from the botom up until the oil comes out the top do not fill from the top you will have air potckets and that would be bad for your drive. When I did mine I used the break bleeder kit from a master cylinder i replaced on my van it worked great. By the way the only dumb questions are the ones we didn,t ask

Thanks Alot. By any chance do you remember how much oil went in before it was full?

not sure but I think one quart should do it but mine was a 40 HP never mix oils use the same kind if you need more than a quart

again do NOT FILL FROM THE TOP You more than like ly will not get it full and you will destroy your outdrive
