13. Installation Instructions
Prestart Checklist
1. Check engine, transmission and V-drive (if applica-
ble) oil levels. Also check for any oil leaks and repair
as needed.
2. Check that all engine drain plugs are installed and
tightened. New engines may be shipped with drain
plugs removed
3. If engine is equipped with optional closed
cooling system, check for proper coolant level.
Closed cooling systems must be filled with a 50/50
mixture of ethylene glycol based anti-freeze and
clean fresh water. (See Routine Maintenance
Section for “Filling” instructions) When proper-
ly filled, ensure that any/all fill caps, fittings and
hoses are properly secured and not leaking.
4. If engine is raw water cooled check the system for
leaks and correct as needed.
5. On engines equipped with Electronic Throttle
Control (ETC) there may be a cable routed from
the throttle control lever at the helm to a potenti-
ometer located in the engine compartment. Make
certain that this cable operates freely and is
properly adjusted. The adjustable potentiometer
stop screws must not be used as the stop for
the throttle lever/cable assembly at the helm.
6. Check the transmission shift cable/lever adjust-
ment on Inboard, V-drive and stern-drive applica-
tions with mechanical shift. If the transmission
is equipped with electric shift, check for proper
operation of the shift solenoids (ahead and astern).
Refer to your transmission operation manual.
7. On inboard, V-drive and stern drive applications
verify that the engine will not start unless the shift-
er is in the neutral position.

of the reverse bucket and adjust as needed.
9. Inspect the fuel system for leaks and repair as
needed.
