Which Gear Oil Weight

[mmarino]

I have the 1973 Merc 200 I've been posting about lately. Went to my Merc dealer to get a manual, all out. Does anyone know which weight gear oil I should put in? Any recommendation on the brand? Is the Walmart Supertech worth buying?
Thanks guys!

I"m pretty sure they're all 80-90, don't think there's an option. As for brand, I've used the ST with no problem, but considering the cost difference and how little is needed I go with a top shelf to feel better. Any you use will likely work as long as its marine.

Thanks, at Wal-mart they offer 80-90 and 85--140. Wasn't sure which weight. Anywhere else to look?
