89 johnson gt 150 gear oil

Hello I just bought a new to me boat with this motor I was wondering what gear oil weight I need to put in the lower unit? Should I put quicksilver in or ams oil? Thank you for for insight and help.

That is a mechanical shift motor, right? Use any marine grade gear oil for mechanical shift motors.

As for two cycle oil, use any TC-W III rated 2 cycle oil. Amsoil is not TCW rated, or at least is wasn't the last time I looked.

Quicksilver High performance, SAE 90, gear lube will do nicely

( High Performance, rather than Premium, being recommended for motors over 75 hp)

Use the best oil you can find.----See your BRP / Evinrude dealer.----Gears , bearings and shafts are expensive and no point penny pinching on oil.

any quality 80w-90 marine gear lube will work

Notice that all suggestions have the word marine in them and not automotive. Quicksilver or Amsoil will do fine....
