Trim works fine, but when trim reaches the point where the engine would tilt up, it wont continue moving up without assistance. If i help it, i can stop it at any position and it will hold, and it moves down from full up position fine, just wont tilt up on its own. Switched the pump assembly from 1 engine to the other to rule out motoe or trim cylinders. Definately the pump assembly, and it is assembled correctly, but i dont know enought about the pump to know what is wrong. Anyone have any suggestions? You can see the schematic for the pump assembly at http://www.yamaha-motor.com/outboard/parts/home.aspx and choose outboard, 2002 outboard, and vz150tlra, then choose power trim&tilt assembly 2
