mike rousseau Posted September 1, 2013 Report Share Posted September 1, 2013 I was told at 100/1 some had issues... I had a 9.9 that said 100/1 and I mixed 50/1... Never had a problem... Didn't really smoke Link to comment Share on other sites More sharing options...
vance Posted September 1, 2013 Report Share Posted September 1, 2013 My dad had that exact motor and ran it 100/1 .If you ran it wide open for a while and shut it off to fish it was a HARD pull to yank into life.Convinced the oldman to go to 50/1 and there were no more problems. vance Link to comment Share on other sites More sharing options...
porkpie Posted September 1, 2013 Report Share Posted September 1, 2013 I have a 96 Johnson 15 (same motor as Evinrude.) I run it 50-1 and have always done so. I would not run 100-1. I use amsoil synthetic and have very little smoke. Link to comment Share on other sites More sharing options...

aplumma Posted September 1, 2013 Report Share Posted September 1, 2013 If you are using amsoil or an oil that is formulated as 100:1 you are safe. Personally I mix at 80:1 using amsoil in some high performance motors and never had an oil related failure. Art Link to comment Share on other sites More sharing options...
