For those of you with a '92 70hp evinrude, I would like to know what color the wire is that comes from your engine temp switch! Not the sending unit going to the gauge but the switch which triggers the over-heat alarm and sends the motor into S.L.O.W. mode.
I've had intermitting over-heat problems for a year now and bought a temp switch recently which differs from what I had in that the tracer wire color is different.
I guess I'm asking for your visuals from your switch.

Tan would be what came out of mine. The new one I just put in would be tan/blue which is what's called for on the evinrude parts web page. There are other variations in that the wire is color coded differently for higher or lower temps when the switch would open or close setting off the alarm and putting the motor into SLOW mode.
I was hoping that others who had this motor would be willing to tell me what they specificly had on their motor.

Should be tan/blue stripe, changed by Service Bulletin, along with 3or 4 other bulletins for overheating. Prop close to 6000 rpms, lugging this engine kills the middle cylinder.

Thanks for the reply. I'd like to get my hands on these service bulletins and read up on this overheat problem! I hope this will end the nightmare.
Anyone else care to share?
