The resulting position of the anti-ventilation plate
must be 0 to 1 in. (0 to 25 mm) below the boat’s bot-
tom.
Bolt your engine to the boat’s transom using 8 mm
bolts, washers, lock washers, and nuts.
After positioning the engine, use the stern brackets
as a template for location and size of holes to drill in
the transom.
Drill two holes of the proper size through the tran-
som. Be sure to drill holes at right angles to the tran-
som.
IMPORTANT: If the anti-ventilation plate falls out-
side the 0 to 1 in. (0 to 25 mm) range, the installa-
tion is not considered normal. The motor shaft
length must be changed or the boat’s transom must
be modified.
Lower than recommended – serious powerhead Apply a good waterproof caulk generously behind
damage could result from water entry into the lower
engine cover or overloading from an under-revving
propeller at wide open throttle.
Higher than recommended – serious powerhead
damage could result from inadequate cooling or an
over-revving propeller. Propeller ventilation (slip-
page) often occurs, resulting in poor boat perfor-
mance.
On a specialty hull, non-planing hull, or on a boat
with a curved transom, these guidelines might not
apply. See your DEALER for special installation in-
formation.
the heads and to the shanks of the mounting bolts
before inserting them and to the surfaces of wash-
ers that contact the transom. Avoid RTV silicone
and polyurethane sealants as they can be dis-
solved by gasoline.
Secure the engine with the mounting hardware po-
sitioned as shown.
After 30 minutes of operation, retighten clamp
screws by hand. DO NOT use tools to tighten clamp
screws. Check clamp screws regularly.
WARNING

When replacing bolts, screws, and other
fasteners, use Evinrude/Johnson Genuine
Parts or parts of equivalent strength and
material.
Center the engine on the boat’s transom (or mount-
ing bracket) and tighten the clamp screws by hand,
NOT with tools. See your DEALER for an accesso-
ry transom plate to protect the boat’s transom.
