Lower unit oil for 2003 115 2 stroke

[tom s]

Can't find recommended lower unit oil for my motor. What oil can I substitute?

In my opinion these gearcases are not robust like earlier versions.----Use the best oil you can find at a BRP / Johnson / Evinrude dealer.----Or Mercury ---" High performance " ---will do as well.

Mercury or Quicksilver "Hi-Performance" (sae 90) gear lube as Racerone suggests , rather than the "Premium" grade which is only suitable for engines less than 75 hp

I think I am right in saying that the Hi-Performance and Premium grades should not be mixed
