Answer 3

just buy a quart of lower unit lube,  drain the old, put the squeeze bottle in the lower drain hole,and squeeze the bottle untill lube comes out the top hole,  put the top plug in, then remove the squeeze bottle and quickly put the bottom plug in. One bottle of lube is perfect size for 1 lube change.

Answer 4

I not promise the link correct, but, this been a good site for information. This an 85, but, I bet it about the same.

Takes about 27 to 30 oz of marine gear lube.

There about 32 ounces to a quart.
