Mercury Outboard Control box and cable Mercury part # 65640A15 V175 and V200 from 1978 150hp tilt/ trim/ key, very good condition This came off a 1978 Merc V6 150 hp that broke a piston and stopped. It is from a freshwater motor I used to own and It has been in dry storage for 40 years out of the sun. It looks like new inside. Only defect I can find is a small break in the outer casing of the cable as can be seen in the picture. I have not tested this control box but I have every reason to believe it is good.
