Trim Tabs

Mount your trim tabs to the transom so that they are
flush or just a hair up from the bottom.
Also mount them so that they are 1/2inch from the
outside of the hull.

Turn fin

The  turn  fin  should  be  mounted  on  the  extreme  right
side  of  the  transom,  above  the  trim  tabs.  Make  sure
the  fin  is  90  degrees  to  the  bottom.  It  will  be  canted
outward with the hull level.
