I am gathering the parts I need to get my engne running again. Its a 1986 200hp Evinrude.
I remember that this engine put out a very noticable cloud of smoke everytime I used it. Ive had it for 20 year now. Before it broke down, two years ago I heard that one could use synthetic two stroke on outboards, but never got to try it.
The VRO was eliminated many years ago and Ive always mixed in tank to a 50:1 ratio (3 ounces per gallon+/-).
I did the sea foam treatment a few times but after a couple of uses it was smoking again like before.
Will synthetic two stroke oil reduce the smoking and or benefit in lubrication of my engine?
Should I reduce the ratio to 75:1 or raise it to 25:1 with sythetic oil?
