I have a 1983 19' Doral with a 1983 3.8l V6 OMC and OMC outboard. The question I have is with regaurds to the way the boat steers. At low (idle) or non wake speeds the boat will not run straight, I have to continually turn the wheel back and forth (almost full turns) to keep it relatively straight, other boaters must think I'm drunk... At any speed over 10mph this problem is gone. The outdrive seems tight when down and engine off. Any idea where to look, or is this normal?
