1950s Champion motor hydro drive (identify model/year)

[Bobmack]

I just acquired what appears to be a 4.2hp hydro drive Champion motor with a two-bladed bronze prop, model #2LHD-2769. The only information I can find is that these motors were made from 1950-1952. 1950 was a single hydro drive; 1951 and 1952 were hydro drive super dlx. This motor also has an automatic recoil pull start. Does anybody know which model it is; how do I fill the gear case, and which oil should I use?

Thank you.

My info says its a 51.I think the guys at www.aomci.org can probably help you with hydro
drive oil.

My book says it takes "Champion Lower Unit Oil". It doesn't explain what that is.

However, the 1953 Hydro-Drive says Champion Lower Unit Oil, --OR-- Extreme Pressure Outboard Gear Oil EP-90.

Sounds like they gave away their little secret, huh?
