2007 Johnson 2.5 hp R4 4-Stroke Outboard Owners Manual

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.
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.
Drill two holes of the proper size through the tran-
som. Be sure to drill holes at right angles to the tran-
som.
Lower  than  recommended  –  serious  powerhead
damage could result from water entry into the lower
engine cover or overloading from an under-revving
propeller at wide open throttle.
Apply a good waterproof caulk generously behind
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.
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.
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.
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 infor-
mation.
WARNING
INSTALLING THE ENGINE
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 accessory
transom plate to protect the boat’s transom.
