I have a 150 Mariner 1986 model. The Trim Gauge is inoperative, I have a Seloc Manual but I cannot seem to find out where the sending unit is located. Are there any tips that anyone has for diagnosing the actual problem?
I just looked all through my Seloc manual and could not find the location of the sending unit. I have the same motor. My neighbor also has the same motor, I'll ask him if he knows the location next time I see him.
