My motor will not trim up, it is a model E200LHAFA. The pump runs when pressing the trim up button, but it does not trim up, it will trim down all the way, it only goes up about 10%. I have already ruled out the manual release valve and checked the fluid. I think it is internal in the valves. I want to replace the entire unit and I am very confused by the diagrams and descriptions for the parts part # 5009808 appears to be the complete unit, 5009818 says see DPS manifold assembly. Which do I need?
