INSPECTION
IBR SYSTEM FUNCTIONAL TEST
Test on Dry Land
NOTE: This test requires two people. One person
to start watercraft and operate controls, and one
person to observe iBR gate movement.
1. Provide adequate ventilation of exhaust gases
or move watercraft outside.
NOTICE
Do not install an exhaust ventilation
hose in the iBR gate area or damage may oc-
cur when the iBR gate moves downward dur-
ing operation.
2. Connect a water hose to the watercraft to pro-
vide exhaust system cooling when operating
engine. Refer to
EXHAUST SYSTEM
subsec-
tion for procedure.
NOTICE
– Ensure there are no tools or other object that
may interfere with the iBR gate movement.
– Do not run watercraft for more than 2 min-
utes out of water or damage may occur to
drive shaft seal carrier.
WARNING

ment must stand to the side of the stern well
clear of the iBR gate and pump nozzle, and
in full view of the operator.
