most of the boats i saw with the tabs mounted this way were either full race boats or high end poker runners. my first thought was that the tab would be on a pretty steep angle before it was really in the water. but after i thought about it a bit longer i realized that the outside edge of the plane is always at the water and as the plane is lowered oncoming water "see's" an increase in plane width as its angle is increased. now this makes sense and the tab might have a variable effect as it is lowered. the lower the tab is the more "width" is avaliable to the running surface. any of that make sense?

It makes sense but it looks strange

No Offence LOL

Too Old, I think you are correct. They told me to move my tabs in as close as possible to the drives, that way you have more tab in the water to affect the handling. But will you advesly affect the speed ?

Too old that sounds like it makes sense, theres gotta be some reading this board that knows for sure. Greg

Yeah, I mounted my tabs in close to the outdrive but even with the hull "V". It's working well for me and I have totally lost that nasty off plane "bow hunt" or "idle wander" thing. I'll just bet that everyone's situation is going to be a bit different and that there is really no "fitsall" answer to this one. --- Jer

That is my boat,
This causes transom lift therefore less drag in turns and running thus results faster boat. This is how it was explained to me. I had expert rigging from rick at total marine in tuckerton,NJ. Only 1.6 hours on 496HO so got some breakin time to go, But running 69 MPH, on Gps @
4000 rpm this boat rides and turns like it is on rails.
Also 3" high x dimension.

PS. these Dana tabs are a great value
