INSTALLATION AND PREDELIVERY
OUTBOARD INSTALLATION
Transom Measuring and Drilling
Hull Centerline
Locate the centerline of the boat transom as it
relates to the hull (bottom) of the boat.
Use a straightedge to draw a
line connecting the
port and starboard chines. The chines
should be
used as reference points for determining the cen-
terline
of
the hull.
Use a framing square to accurately place a line
on
the transom. The centerline of the hull should be
in
line with the keel of the hull and perpendicular
to the midpoint of the
line connecting the port and
starboard chines.

Transom Heights
Make sure the transom height is consistent with
the height
of
the outboard to
be
installed.
•
A 19 to
21
in. (48.3 to 53.3 cm) transom height
uses a
20 in. (50.8 cm) shaft outboard.
• The shaft length of the outboard being installed
should
come close to matching the transom
height
of
the boat.

Determine transom height by measuring from the
top edge of the transom,
along the centerline.
Use a straightedge as a reference to extend the
bottom
of
the boat.
Position the straightedge
along centerline. The
distance from the top edge of the straightedge to
the top edge of the transom
is
the actual transom
height.

Transom Drilling Locations
Use the outboard stern brackets as a template for
location and size
of
holes to drill
in
the transom.
Center the outboard
on
the transom (or mounting
bracket) and tighten clamp screws by hand. An
accessory transom
plate is recommended
to
pro-
tect the transom.
Using each stern bracket's mounting
holes as a
guide,
drill holes through the transom.
Drill one 11/32
in.
(8.7 mm) hole for each side.
IMPORTANT: Be sure to drill the required holes
perpendicular to transom surface.
