Re: bennett m120 tabs vs normal tabs
Snowman,
You would not be able to notice any difference in performance between the 12 x 12 and M120 system on your boat.
The 10" x 12" M120 generates just about the same amount of lift as the standard 12" x 12" Trim Tabs. This is due to the downward facing fins on each side of the Tabs. These fins capture water pressure that is usually lost out the sides of a flat Tab and channels it aft to create additional lift. With it's smaller mounting footprint the M120 is often easier to mount on a transom that may have a transducer and or speedo pickup mounted on it. Additionally the fins limit the spray thrown out the sides of the Tab, allowing it to be mounted closer to a transducer without creating interference.
The M120 comes standard with shorter actuators (rams) than the 12" x 12" making it much easier to mount under a swim platform if you have one on your transom.
We simplified the hydraulic connections in the M120 allowing them to be installed without needing to access the inside of the transom. The tubing is connected directly to the actuator before it is installed and pushed into the boat where is is connected to the hydraulic power unit.
I hope this is helpful, let me know if you have any other questions.
