I have been using Mercury High Performance Gear Lube + in the lower unit for years. Last time I bought any I got several qts.
Now I am down to my last few qts. and am looking for more. When I put in the part number I get Mercury High Performance Gear Lube.
SAE 90. I think it is the same thing but need to make sure. Part no. is the same on both bottles Part no. 92-858064K01
