lower unit grease help

[mxfreak117]

i bought a late 70s, or early 80s, chrysler 25 outboard. I'm not sure of the year because I'm not sure how to find out. But in my service manual it does not give the type of grease to use in the lower unit. Can anyone give me any help? I no since than its gone to more of a oil than a grease, but I think I need a type of grease for it. Anyways, I'd appreciate any help you can give.

Thanks

i bought 80w-90. This seemed to be what most people were using. I was just a tad worried if i would need a thicker oil because my outbaord is so old... any thouhts?
