Not sure on your Lenco tabs ???
Bennett recommends as far outboard as possible !
They will be working like a teeter totter the way they are now..
Lil' Kenny has the same set up with Bennett hydraulic tabs.
He was freaking out when I took the hole saw to his 3K bracket..
Also Jr. hit 48 MPH with the Merc 250HP with this setup..
He has since upgraded with the 300HP Zuke...
He is well over 50 MPH now !!
