I am running a 1975 Johnson 115 on a 15ft Phantom Ski boat. I am having some problems with the tilt and trim. I just replaced the old motor with a new one and it is suppose to be a plug and play model. I have all my wires hooked back in and put fluid back in also. I am not able to get the unit to do anything, when I hit the up botton all I hear is a click that is coming from the silenoid and when I hit the down button I get nothing. Can anyone give me a suggestion on what I may have done wrong.
