i havent bought a manual yet. so need help.what kind of oil do i use for mercury 200 20hp lower end?lower end oil or 80/90 something weight?gear lube.thank you.philip
There are twoo you can use. Standard 80/90W oil is fine but the Quicksilver Premium L/U oil will run a tad cooler and do a better job. It's green in color and stinky!!! But it's good stuff.
