Section 11 LUBRICATION SYSTEM (2-STROKE)
Subsection 02 (OIL INJECTION PUMP)
All Engines except 947 DI
Run engine at idle speed while manually holding
pump lever in fully open position. Do not activate
throttle lever.
947 DI Engines
– Use the VCK (Vehicle Communication Kit)
(P/N 529 035 981). Look in the MONITORING
section of the B.U.D.S software.
– Use the “Oil lines bleeding” function that al-
lows to “lock” the engine RPM in idle speed
while the throttle is fully depressed to ease the
bleeding operation.
– Since oil cannot be seen through the small oil
lines, press and hold the vehicle throttle to wide
open position for 45 seconds.
All Engines
CAUTION: If watercraft is out of water, engine
must be cooled using the flush kit.
CHECKING OPERATION
On Watercraft
NOTE: Oil line supply must be full of oil. See
bleeding procedure above.
Start engine and run at idle while holding the pump
lever in fully open position.
All Engines except 947 DI
Oil must advance into small oil lines.
All Engines
NOTE: The engine should have a rich mixture,
idling irregularly and emitting smoke at exhaust
outlet.
If not, remove pump assembly and check the
pump gear (717 engine) or shaft (787 RFI and 947
DI engines) for defects, replace as necessary.
Test pump as described below:
NOTE: Through normal use, oil level must not
drop in small tubes. If oil drops, verify check valve
operation. Replace as necessary.
Bench Test
Connect a hose filled with injection oil to main line
fitting. Insert other hose end in an injection oil
container. Using a counterclockwise (reverse po-
sition) rotating drill, rotate pump shaft. Oil must
drip from fittings in parts of rotary valve cover
while holding lever in a fully open position.

3. Counterclockwise (reverse) rotating drill
4. Oil must drip here
For an accurate test, each port should be checked
separately to ensure equal delivery on both ports.
To obtain a precise result of the oil pump delivery
rate, rotate it counterclockwise at 1500 RPM for a
total time of 5 minutes.
NOTE: To ensure accuracy of test, oil lines should
be completely filled before starting test.
Compare the results with the chart below. If oil
pump is out of specification, replace it.
