I know that I can use air to blow out the line but I cannot find the line under the dash to blow out the dirt or ?. Where does the line from under to dash connect to the boat or motor 2009 Z7 150 Merc.?
When my did this it was because the water impeller was bad. Had to replace it and then had bass pro reset my computer on the motor took car of the problem.
I have 2009 Z7 had the same problem. I just went ahead and put hydraulic steering put on it. This is the only way to go. Steer with one hand in either direction.
The ones from Northern Tool fits the z7 trailer. All I had to do was push out the ones that the trailer came with and unplug them. The new ones are water proof and have the same plug the the ones I took out had. No tools needed.
This sounds about the way my year has gone. Best fishing this year was in the Bahamas with my son who lives there. Hope the weather cools off so we can get back to fishing here.
