I took a 1992 75 hp Mercury off my boat and put a 1995 115 hp Mercury on it, and used the 75 hp wiring harness.
The 115 hp runs now but tachometer won't work. Is it the wiring harness? Is the 115 hp (runs on 2 cylinders until it reaches certain rmp, then 4 cylinders) not compatible with the 75 hp tach? How do you trouble shoot this?
Thanks, Scott
