Transom Measuring And Drilling - BRP Evinrude E-Tec Series Service Manual

INSTALLATION AND PREDELIVERY
OUTBOARD INSTALLATION
Transom Brackets and Jack Plates
When mounting an outboard on boats equipped
with transom brackets or jack plates, refer to the
manufacturer's recommendations.
Confirm maximum weight and horsepower
•
capacities.
Jack plate assemblies must provide a one-piece
•
mounting surface to support the outboard,
hydraulic unit, and steering system.
Mounting Hardware
WARNING
Use all mounting hardware supplied with
the outboard to help ensure a secure
installation. Substituting inferior hardware
can result in loss of control.
The required outboard mounting bolts, aluminum
backing plates, washers, and nuts are used to
attach the outboard to the frame of the shipping
palette.
Refer to the outboard's parts catalog for alternate
length mounting bolts or replacement compo-
nents.
Use only Evinrude/Johnson Genuine Parts or
•
parts of equivalent type, strength, and material.
Use the mounting hardware provided with out-
•
board whenever possible.

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.

Dual-Outboard Centerlines
The following table lists standard ABYC centerline
spacing between outboards in dual installations:
V4 and V6
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.
