Hello. I am trying to flush and replace the oil in the lower unit, but I can't seem to find the exact answer.
I came across PDF file from mercurymarine.dk that says to use "Quicksilver Premium Gear Lube 80W-90 For Outboard lower units below 75hp". (mines 90). Then towards the bottom, it says to use "Quicksilver Premium Gear Lube" for all Force engines.
The 2 statements seem to constrict each other, and I can't seem to confirm which oil to get, Premium or High Performance.
