Running the Outboard Using a
Hose and Flushing Adapter
A flushing adapter may be used to provide cooling
water when running the outboard to:
•
Flush the engine
•
Run for an extended period of time, such as
when performing diagnostic work
•
Run the engine on a dynamometer
•
Prepare the outboard for storage.
IMPORTANT:
The outboard must be located in
a well ventilated area with appropriate ground
drainage.
Keep water inlet pressure between 20 to 40 psi
(140 to 275 kPa).
Be sure water supply is sufficient to run the engine
above idle speed.
Water Supply Requirements
1. GPM: Gallons per minute
2. LPM: Liters per minute
Install flushing adapter onto gearcase water inlet
screens.
Temporarily cover the two small
holes on each side of the gearcase with water-
proof tape to make sure enough water travels
to the powerhead. Water can drain from auxil-
iary inlets, resulting in engine overheat.
A steady stream of water should flow from the
overboard indicator while the engine is running.
Monitor engine water pressure gauge when:
•
Engine speed is above 3000 RPM
•
Running engine on a dynamometer.
Engine will overheat if normal water
pressure is not maintained. Temporarily install
an engine water pressure gauge if not
equipped with one.
Be sure to remove waterproof tape from auxiliary
water inlets.
Engine will overheat if auxiliary
water inlets are restricted when outboard is
back in service.
WARNING
To prevent injury from contact with rotat-
ing propeller, remove the propeller before
running engine with a flushing adapter.
