TROUBLE RECOVERY 5
JET PUMP CLEAN-OUT
PROCEDURE
WARNING
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, forward thrust will decrease. If this condition 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 projec- tion in the access port wall.
