INSTALLATION
TRANSOM HEIGHT
Make sure the transom height matches the
length of the outboard to be installed.
WARNING
The outboard must not exceed the
maximum horsepower indicated on the
boat’s capacity plate. Such overpower-
ing can cause loss of control. Contact
the boat’s manufacturer if your boat
lacks a capacity plate.
•
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 match the transom height of
the boat.
•
Boats designed for remote-steered out-
boards might be overpowered by a
tiller-steered outboard of the maximum
rated horsepower. Refer to the boat
manufacturer if you are unsure.
Determine transom height by measuring from
the top edge of the transom, along the center-
line.
Incorrectly matched boat and outboard
transom heights can cause boat insta-
bility and loss of control. Refer to Tran-
som Height.

Prevent lateral movement and possible
outboard loss by using the mounting
hardware supplied or hardware of suffi-
cient size, strength, and quality. Refer
to Installing the Outboard on page 40.
2
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.

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.
Test outboard and boat performance at differ-
ent heights until the best performance is
achieved.
IMPORTANT: Use an appropriate hoist to lift
the engine. Refer to Specifications on page
38
for engine weight.
IMPORTANT: Be sure that outboard water
pressure is not adversely affected by the
mounting height of the outboard.
