So I have a 79 Apollo with 305 mercruiser 898. The trim pump is actuating and running the drive down add soon as the key is turned on. When the drive hits the maximum that it can go down the pump continues to run trying to push the drive down father. .. Any ideas?

As the trim pump wiring and the engine harness wiring should be independent, start by looking for damage in the harness. Also need to ask, what style trim controls do you have? 3 buttons on a separate panel, or trim switches in the throttle handle?

3 button on a separate panel. I have checked for damage everywhere. It worked perfect Friday. Saturday morning it started doing what I explained. I did leave the radio on and the battery control on. So the battery died... Would this cause the issue? Charged the battery back up and the problem persists.
