Installation; Transom Height - BRP 2011 WRL User Manual

Product Information
WARNING
Your outboard must not exceed the
maximum horsepower indicated on
the boat's capacity plate. Such over-
powering can cause loss of control.
Contact your Dealer or the boat's
manufacturer if your boat lacks a
capacity plate.
Boats designed for remote-steered
outboards might be overpowered by
a tiller-steered outboard of the maxi-
mum rated horsepower. Ask your
Dealer or boat manufacturer if you
are unsure about your boat's suit-
ability.
Incorrectly matched boat and out-
board transom heights can cause
boat instability and loss of control.
Refer to

Transom Height

Prevent lateral movement and pos-
sible outboard loss by using the
mounting hardware
hardware of
strength, and quality. Refer to
ing the Outboard
A mounting surface that is damaged
or too thin to support your outboard
while underway might fail during
operation, causing a loss of control.
Be sure the boat's transom or
mounting bracket is structurally
sound and between 1 5/8 in. (41 mm)
and 2 3/4 in. (70 mm) in thickness.
NOTICE
Use an appropriate hoist to lift
the engine. Refer to Specifications on
page 51 for engine weight.

TRANSOM HEIGHT
Make sure the transom height matches the
length 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 out-
board.
• The shaft length of the outboard being in-
stalled 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 center-
line.

3. Transom Height
Boat performance depends on outboard
mounting height.
Generally, the anti-ventilation plate of the
gearcase should align with the bottom of the
hull. Conventional V-hulls often perform well
with the anti-ventilation plate approximately 1
in. (25 mm) above the bottom of the hull.
Test outboard and boat performance at differ-
ent heights until the best performance is
achieved.
IMPORTANT: Be sure that outboard water
pressure is not adversely affected by the
mounting height of the outboard.
