I have an 88' Sun Runner with a Volvo Penta 290 outdrive. My outdrive will not move up when I am running on the water, speeds fast or slow. It also leaks down. What do I have to do to fix this?
It's "probably" a bad trim pump or leaking valves. There is a slight chance that it could be the trim cylinders, but have never seen it happen on a 290, but that doesn't mean it hasn't.
