Before selecting a mounting location verify proper clearances inside (transom mounted compo-
nents, etc) and outside (turning drive and propeller clearance) of the boat. Do not mount tabs
in the chine area.
NOTE: The farther the tabs are between each other the better, this will allow you to achieve
the maximum performance out of your tabs.
