Which gear oil do I use?

[Robert Jordan]

I bought a new 2010 75 HP Optimax last December for my 2002 PT 175 Tracker and I want to change my lower unit gear lube. What gear lube is the correct one for this motor? I don't want to do anything to damage my motor or void my warranty.

Either Premium blend OR Hi-performance, both Merc products.

Bob, I take it both are within my warranty specifications. Our local Walmart carries the Quicksilver High Performance. Is this okay? I live nearly 40 miles from my local Mercury dealer and with my schedule and the price of gas it is hard for me to get over that way very often. I bought enough Opti oil from them when I bought the motor last winter to do me all year. Thanks for your help.

That would be fine....
