I have to make a decision. Your input is appreciated. I have a rebuilt 1993 200 hp evinrude, I have diagnosed that my fuel/vro pump is not working properly. There is a kit that allows me to replace the pump with a fuel only pump ( it is also 100.00 less exspensive )than a new fuel/vro pump. Obviously if I go fuel only I have to pre-mix the fuel and oil. Any thoughts would be appreciated.
