No, I dont think your 1969 Merc came w Tilt or Trim, it will have to be added from a compatible Merc donor motor. And that donor motor's remote throttle might work w your motor. Off hand, I suspect the T and T will need to be via a seperate switch, not on the controls, esp if the donor motors controls wont adapt to your 1969 Merc. Dont know if they will or wont.
