I am having a serious trimming problem. When I throttle up. My tilt starts to drop and never lets me plane out my boat at all. I have a 1986 Winner 18' center console. I replaced the tilt unit and it does the same thing as the old one. All appears fine. But I'll be darned if I can figure this out at all. I talked with a friend and he told me about a voltage regulator that could be the cause. Any thoughts? I am really bummed and stumped
