I'm new Fiberglassics, so if I post this incorrectly please forgive me.
I bought a '75 Mercury 1150 to install on my '76 Ranger 175a bassboat, and since I am replacing the '77 850 merc on it I'm fixing the most common issues I have seen with older motors.   I have already replaced the fuel lines, stator coil, rebuilt the carbs, replaced the impeller and the wiring harness is new as well, also rebuilt the fuel pump.  What I have noticed before I turn the key and fire it up is the switchbox has leaking black goo coming out of it.  I was guessing most likely it was
some capacitor leaking from the inside or something.  Will this cause a problem with the switchbox shorting out????  If so does anyone have a switchbox in good condition?   I would feel a lot better with a non gooey switchbox on my motor in the first place.  I am setting the motor up to be in GOOD condition so it is as reliable as my 850 merc is.  Any information, help, or
things to look for would be great.
 I also am in need of a timing belt.  I know I can get a new one for 30 bux, but if you don't ask u never know.  any information you guys would have would be great.
Brent.
