What type of Lubrication?

[odyaxchad]

I have an 1976 Century 4000 21', I know it to be an OMC outdrive, not certain the year of outdrive, believe it to be a 1976..... has the cone and cotter pin to secure prop...
What lubrication do I use...manual says, "C" type.... I ordered Sierra type c blend, will this work for upper and lower gear cases?

Per chance would anyone know the WOT rpm, and thus the best pitch for prop?

Thank you Gentlemen.

You have an electric shift Stringer drive. Use that type C lube in the lower gear case only. Use GL5 rated 80w90 marine lube in the upper and intermediate gear cases.
