Yamaha 2002 150hp - VX150TLRA

Repair Difficulty
Repair Time
1 to 2 hours
Parts lookup was easy to do and I completed my order with no problems. My specific make, year and model was easy to find and the section on the tilt and trim was easy to read and find the needed parts.

Problem fixed: Tilt/Trim would not move

Placed engine on safety tabs. Removed the caps on the 2 trim cylinders and the one tilt cylinder. Removed the 3 rods and replaced the O-rings, dust seals and back up rings. Installed the rods back into the cylinders and installed and tightened the cylinder ends. Replaced the fluid in the reservoir and bled the air from the system. Motor moved up and down with no hesitation or signs of fluid leakage around the cylinder ends!

Great experience, seals arrived without delay

Problem fixed: Hydraulic trim/tilt unit seeping fluid at one of the trim actuators

Ordered seals associated both trim actuators and tilt actuator. Replaced seal on leaking actuator and other actuators as a preventative measure. As a retired aircraft mechanic this type job was easy.
