Hi I just bought a 94' sabre 245 it has the Merc Alpha One 4.3 L LX drive in it. The guy who owned it had passed away and his son sold the boat. The question I have is about the power trim/tilt, the control for it is on the shift lever and it works fine in the trim range but stops at full trim up position, that uses about 2-3" inches of the rams travel. How do I get it to tilt up for trailering? I have Volvo aq drive in my old boat and it has an additional switch you have to press along with the trim up switch. I can't find any such switch on this setup. Anybody got any idea?
