My 150 1998 Evinrude tilt ram works fine up and down. The trim rams are fully extended and won't retract. The unit sat unused for about 12 months. The fluid has been topped off and the motor runs fine in both directions. Are there valves in the unit that may be stuck? Can the unit be flushed with a solvent?
<br /><br />This is an engine trouble. I will move it to Evinrude troubles.
