Before launching the boat, carefully
11 12 13 14
check the jet intakes under the boat for
21 22 23 24
weeds, debris, or anything else that
21 22 23 24
31 32 33 34
might restrict the intake of water. If the
intakes are clogged, cavitation could
31 32 33 34
41 42 43 44
occur, reducing jet thrust, and possibly
41 42 43 44
damaging jet pump parts. In some
51 52 53 54
cases, the engine may overheat
51 52 53 54
because of a lack of cooling water, and
damage could result. Engine cooling
water is fed to the engine by the jet
pumps (see page 3-10).
Refer to Jet Pump Clean-Out proce-
dures on page 5-5 before attempting to
remove weeds or debris from the jet
intake or impeller areas.
WARNING
Rotating parts could cause severe
injury or death. Before attempting to
remove weeds or debris from the jet
intake or impeller areas; shut off the
engines, remove ignition key, then
remove the engine shut-off switch
cord from the shut-off switch.
