Test Run Procedure
!
CAUTION
When engine is started, IMMEDIATELY check that wa-
ter pump is operating. Operation of water pump is indi-
cated by water discharging from “tell tale”.
1. While test running outboard, check powerhead as-
sembly for leaks and/or unusual noises. Make any re-
pairs BEFORE placing outboard in service.
Important Information
Proper break-in assures that all moving parts “wear-in”
evenly to ensure a longer engine life and optimum perform-
ance.
Operate your new outboard motor at varied throttle settings
– not to exceed 1/2 throttle (2500-3500 RPM) during the
first hour or the first five gallons of break-in fuel. Refer to
“Fuel Mixture and Gasoline/Oil Recommendations” –
“Break-In Fuel Mixture” located in your operation and Main-
tenance Manual.
During the second hour operation, or the second 5 gallons
(20 Litres) of break-in fuel, operate the Outboard at varied
throttle settings not to exceed 4500 RPM.
DO NOT OPERATE YOUR NEW OUTBOARD MOTOR
AT FULL THROTTLE UNTIL THE SECOND HOUR OF
BREAK-IN IS COMPLETED.This includes full throttle ac-
celeration, pulling waterskiers, or wide open throttle run-
ning.
After the first two hours of running, approximately 10 gal-
lons (40 Liters) of fuel, full throttle operation may be at-
tained, but not sustained, for the remaining break-in fuel
(approximately 5 gallons).
For the next five hours of operation, full throttle operation
may, again, be attained, but it is strongly not recommended
for sustained use. (Not more than 5 minutes of continuous
wide open throttle.)
!
CAUTION
SEVERE DAMAGE to your engine can result by not
complying with the preceding break-in procedures.
