Jet unit

Carefully check the jet intake for weeds,

debris, or anything else that might restrict
the intake of water. If the intake is clogged,
cavitation could occur, reducing jet thrust,
and possibly damaging the jet pump. In
some cases, the engine may overheat
because of lack of cooling water, and dam-
age to the engine could result. Engine cool-
ing water is fed to the engine by the jet
pump. (See page 5-3 for jet intake cleaning
procedures). 

WARNING

@

Keep away from intake grate while
engine is on. Items such as long hair,
loose clothing, or PFD straps can
become entangled in moving parts
resulting in severe injury or drowning. 

Stop the engine and remove the clip
from the engine shut-off switch before
removing any debris or weeds which
may have collected around the jet
intake. 

@

EJU9001a

Engine shut-off cord (lanyard)

Check that the engine shut-off cord is not

frayed or broken. If the cord is damaged,
replace it; never try to repair it or tie it
together.
