I have a 1993 24' Chaparral with a 5.7l engine and a Volvo Penta Duo-prop outdrive (DP-C or DP-C1 not sure?). I have been having trouble with the tilt/trim. The down was working fine but the unit would not go up. I have replaced all 4 relays, the potentiometer, and I have cleaned all the electrical contacts I could find. The unit now goes up and down fine, but it automatically stops about 2 inches from the black rubber bumper.<br />Any ideas?
