JET PUMP CLEAN-OUT

PROCEDURE

SEVERE INJURY OR DEATH MAY

RESULT IF YOU IGNORE ANY OF

THE FOLLOWING:

● Turn off and remove both ignition

keys, remove lanyard, and wait for

all movement to stop before

removing access port caps.

● Never override interlocks to run

engine with hatch open.

● The impeller has sharp edges. Be

careful when reaching into jet

pump area.

If weeds or debris get caught in the

intake or impeller, cavitation can occur,

and though the engine speed rises, for-

ward thrust will decrease. If this condi-

tion is allowed to continue, pump

damage can occur and the engines

may overheat and seize. If there is any

sign that the jet intake or impeller is

clogged with weeds or debris, follow

this cleanout procedure.

1) Turn off and remove ignition keys,

remove lanyard, and wait for all

movement to stop.

2) Lift the hatch on the rear platform.

3) Check that the retaining cord is

securely attached to the cap and

retaining strap. Press the release

button and lift the cap up out of the

port. Set the cap where it cannot be

accidentally knocked overboard.

4) Remove any weeds or debris from

the drive shaft, impeller, pump hous-

ing, and steering nozzle. If you can-

not remove the debris, consult your

Yamaha Boat Dealer.

5) To reinstall the access port cap, first

clean off any sand or other foreign

matter from the cap or port surfaces.

Insert the cap so that its slot faces

the bow and lines up with the pro-

jection in the access port wall.
