I am working on a OMC Mercruiser 1979 engine currently. I just got the boat yesterday and the person I got it from said the boat has not been used in over 2 years. My question is that I replaced the battery in the boat and I tried several things, one I tried the tilt but nothing happened except for a click when I push the tilt down or tilt up switch? What is wrong with the tilt? What do I need to check or do? I'd appreciate any help!
