Cutting and Drilling Bottom Foil
Consult the chart on page 13 to see if you need to short-
en the special bottom foil. If you do use a hacksaw to
shorten the special bottom foil by 5 1 /
2
" (140 mm). Make
sure you cut the end nearest the existing holes. Deburr
the foil after cutting.
Tip: there are three dimples in the bottom foil. The upper dimple is a
guide for cutting the foil. Wrap tape evenly around the foil so the top
edge of the tape runs through the center of the upper dimple. Line the
hacksaw blade up with this edge of the tape. The side of the blade
facing the lower part of the foil should run through the center of the
dimple.
Drill two holes using a 15 /
64
" (6 mm) drill bit. Use the
dimples in the foil as a guide. The center of the dimples
will be at 2 1 /
2
" and 3 1 /
4
" (63.5 mm and 82.5 mm) from
the cut end of the foil.
WARNING
If you make any cuts in the foils
be sure to carefully
clean all shavings from inside
the foils. Failure to deburr or
clean the inside of the foils
may cause them to seize to the
connector during installation.

Foil Length - Read Before Cutting Foil
The foil charts on pages 13 and 14 are based upon the top foil riding over the
shank of a swage eye so it is 1 1 /
2
" (38 mm) to the center of the eye. On some boats
this is not possible–for example–a Norseman, Sta-Lok or Rod terminal eye. If
for any reason your top foil cannot ride within 1 1 /
2
" (38 mm) of the pin center,
shorten the foil length to compensate. This pin center is the upper measure-
ment point of the pin-to-pin length as described on page 8.
