Prestart Checklist - Marine Power 5.3 GEN V DI Owner's Manual

Prestart Checklist

1. Check engine, transmission and V-drive (if applicable) 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 properly 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 potentiometer 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 adjustment on
Inboard, V-drive and stern-drive applications with mechan-
ical 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.
