INSTALLATION AND PREDELIVERY
OUTBOARD INSTALLATION
Transom Measuring and Drilling
Hull Centerline
Use the chines of the boat as reference points to
locate the centerline of the boat transom.
Use a straightedge to draw a line connecting the
port and starboard chines.
Use a framing square to accurately place a verti-
cal line on the transom. The centerline of the hull
should be in line with the keel, and perpendicular
to the midpoint of the line connecting the chines.
Dual-Outboard Centerlines
The following table lists standard ABYC centerline
spacing between outboards in dual installations:
Some applications may require changes in this
dimension to avoid strakes, to adjust for transom
height, or for performance reasons. Best perfor-
mance can be determined only through testing.
Refer to boat manufacturer for recommendations.
If the standard spacing does not allow full steering
travel in a particular installation, it may be neces-
sary to increase the spacing.
IMPORTANT:
Some steering systems may
require additional spacing. Refer to steering sys-
tem manufacturer for recommendations.
The top edge of the transom should be more than
twice the width of the dual-outboard centerline
spacing dimension. Bracket installations may not
require this consideration.
Measure the transom for dual-outboard spacing
after the centerline of the hull is established.
Divide the spacing dimension by two. Use the
resulting number to space the outboard center-
lines from the hull centerline.
EXAMPLE: A 26 in. (660 mm) dual-outboard
spacing would result in two outboard centerlines,
each 13 in. (330 mm) from the hull centerline.
