Just put on a 2002 johnson 150hp. I removed my 1993 johnson 120 hp. Does anyone know where the vac hose for the speedo gets attached to the Johnson 150?I have everything hooked up except for that. I can not find it anywhere..
There should be a small fitting in the very top center of the g/c where you attach the speedo tube. The fitting may be broke off as it's made out of CPS. And no it's not vac, it's pressure.
