1972 Johnson 100hp - Hydro-Electric Lower Unit Oil

[jhetrick55]

I just became the owner, well a week ago, of a 1972 Johnson 100hp engine that is in phenomenal shape. However, with the Hydro-Electric shift I have heard that there is potentially a different lower unit gear oil I will want to use with this engine. Can anyone give me some good suggestions for what fluid to use when I change it out? Thanks in advance!

Type-C gear oil that states " For electric shift use " or a product called " Premium Blend " marketed by Evinrude / BRP.

Thanks, I just found that in a manual that was hidden in the boat!
