INSTALLATION
TRANSOM HEIGHT AND SHAFT
LENGTH
WARNING
Your engine must not exceed the maximum
horsepower indicated on the boat’s capacity
plate. Such overpowering can cause loss of
control. Contact your Dealer or the boat’s
manufacturer if your boat lacks a capacity
plate.
The transom height dimension listed in Engine
Specifications, is the height of the boat transom
your engine needs. This dimension is measured at
the transom centerline, perpendicular to the bottom
of the boat.
Boats designed for remote-steered engines
might be overpowered by a tiller-steered
engine of the maximum rated horsepower.
Ask your Dealer or boat manufacturer if you
are unsure about your boat’s suitability.
Incorrectly matched boat and engine tran-
som heights can cause boat instability and
loss of control. Refer to Transom Height and
Shaft Length.
Prevent lateral movement and possible
engine loss by using the mounting hard-
ware supplied or hardware of sufficient size,
strength, and quality. Refer to Installing the
Engine.

Transom Height
Anti-ventilation Plate
Final position - 0 to 1 in. (0 to 25 mm)
Use this procedure to determine whether or not the
boat’s transom height is correct for the engine’s
shaft length:
A mounting surface that is damaged or too
thin to support your engine while underway
might fail during operation, causing you to
lose 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.
Set the motor on the boat’s transom and adjust the
angle so the anti-ventilation plate is parallel with the
boat bottom. Refer to Motor Angle Adjustment.
