Electronic Fuel Injection Set Up
IMPORTANT: Follow EFI Synchronizing/Adjustment section 2C before attempting
tests on EFI system.
EFI set up procedures must be followed before tests on system are performed (refer to
Section 2C). Improper set up can result in poor engine performance (i.e. uncontrollable
idle speeds, lean sneezing, low power during acceleration or engine will simply not run.)
Failure to properly set up the EFI system can lead to misdirections in solving simple prob-
lems in the EFI system.
Fresh Quality Fuel
Using a remote fuel tank containing a major brand of premium unleaded gasoline, test run
the outboard to eliminate any problems related to restricted fuel supply (clogged lines, mal-
functioning anti-siphon valve, etc.) and/or marginal gasoline.
Low Battery Voltage
Low battery voltage can cause EFI system to deliver fuel in an inconsistent manner.
Inspect battery connections and charging system, refer to Section 2B. The EFI system re-
quires a substantial amount of voltage to function properly. Operating engine at a low RPM
for an extended period of time while operating numerous electrical accessories can cause
low voltage.
