Only if you want the last little bit of speed the boat is capable of doing..
I have seen some other mods that do not weaken the skeg.
There are not a lot of shops who can do this without making the skeg weaker.
I know of 4 that came out of Dallas that the torque tab broke. Including one of mine that broke twice from Dallas once with a local shop...I finally found a guy who welded it and quaranteed it would not break at the weld...4 yrs later its still together.. I have not seen one but have heard of some that the skeg broke diagonal from the top of where the tab was welded down to the front of skeg....depending on how much was to break and how fast you were going, it could----leave a mark....... at least a skid mark in your shorts ..
The Allison mods cuts the sportmaster skag to be shorter and not as long. it also shapes the sides so one is concave the other is convex. it also has the Allison torque tab welded in place.
