Trim Control

Having trouble with my trim control. It is bleeding down. Motor is a 4 stroke 40 horsepower yamaha, approx 4 y.o. No physical signs of damage or leaking. Any suggestions???

Make sure manual release screw is tight. If it is tight then probably a internal leak on one of valves and would need to be rebuilt.

thanks. Any suggestions on suitable candidates for the job? I live in Newcastle.
