lower unit oil - the right oil to use

[marksa1458]

Have a 1968 Merc 500 s/n 2479530 that is new to me. Just changed the impellar and gaskets. Want to make sure I use the right lower unit oil.

Is either of these oils the right one to use?

Also where is a good place to get the nylon lower unit nuts and I need the distributor linkage bolt, nut and washer

Any "Marine Lower Unit Oil" will work fine. Try Ace Hardware for nuts, bolts, washers, they keep a good selection and quite a bit in Stainless Steel. True Value Hardware keeps a lot of fasteners too. Good Luck!

The merc high performance LU oil is a superior product, well worth the extra money.

Second. And you aren't talking about a whole lot of lube to start with. (My 500 holds about a pint) At wally world, they have a slick little pump that Atwood makes that makes putting it in a snap, too.
