I have both in separate boats and hydraulic is hands down the nicest by far. If it could be considered a disadvantage, the only drawback with hydraulic is that you can not grab the engine cowling and turn the motor itself when standing by the stern. ( a complete non issue really) That is what really makes it great, you are not fighting the motor torque throughout the speed range.
I had the zink fall off the 150 one day and never knew until I put the engine up and put her on the mooring and saw that the tab was gone... :icon_eek: :icon_redface:
