Transom Height and Shaft Length
WARNING
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.
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.
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 is 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
Antiventilation plate
Final position – 0 to 2 in. (0 to 51 mm)
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 1/2 in. (38 mm) and 2 1/4 in. (57
mm) in thickness.
Use this procedure to determine whether or not the
boat’s transom height is correct for the engine’s
shaft length:
Lift the engine using the lift grips (NOT the tilt grip
or steering handle) and place it in the center of the
boat’s transom.
