Evinrude 15HP 1992

JimRK Posted 7/9/2009 12:53 PM (#83146) Subject: Evinrude 15HP 1992 Member Posts: 183 Location: Menasha, Wis. Picked up a 15HP Evinrude that was manufactured in 1992. Can anyone verify the oil to gas ratio mix? Should it be 50 to 1 or 100 to 1? Thanks for your help.

I'd run 6-8 ozs of Seafoam with each tank too. JimRK Posted 7/10/2009 8:15 AM (#83162 - in reply to #83150) Subject: RE: Evinrude 15HP 1992 Member Posts: 183 Location: Menasha, Wis.

I used it on Lake Michigan on trips that averaged about 10 hours at a time. Another thing to watch is the fuel lines. The ethanol in the gas absolutely rotted them out from the inside. One time the motor just ran for a bit and quit. Then you could start it and it would run for a bit and die. Turned out to be a piece of the fuel hose broken off and it was covering up the gas inlet nipple like a valve when there was flow. Otherwise it was a really strong motor.
