I have a Yamaha 1989 70hp with power trim and tilt. I behaves like it's ok. But watching the trim, one tube (starboard side) advances slightly faster than the other. both completly advance and retract.

Any suggestions on what is the cause?

Thanks Kevin

normal, just differences in pressure that balences out under a load but won't balance in "free rise"
