So i just bought a 1991 Glastron 19' with a 230A volvo penta inboard/outboard motor. well the trim or tilt does not work . When i hit the trim down button i can hear the hydraulic pump come on but the motor doesnt move, when i hit the other buttons (trim up, tilt up or down) the pump doesnt even come on it does nothing . what is going on here? Im new to inboard /outboard. My last boat was an outboard which in my eyes is simple compared to this one...... I would appreciate if some could explain what the tilt does? And i dont even kno where to start for the trim or tilt not working? So some help would be great.
