Inspection
Do the test with the watercraft tied on a trailer in
water.

connected on the flushing fitting of jet pump sup-
port would not supply enough pressure in the ex-
haust system to properly detect faulty joints in
some cases.
Remove rear access panel.
Start engine and bring engine speed to 5000 RPM.
Check for leaks in joint area of expansion pipe. If
there is exhaust gas or water leak, replace pipe.

to pull expansion pipe out.
Remove/disconnect:

sors.
