MAINTENANCE & CARE 4

SACRIFICIAL ANODES

An aluminum alloy anode is mounted on each jet pump outlet on your boat. Galvanic corrosion can damage metal surfaces below the waterline on any boat, particularly in saltwater. These “sacrificial” anodes are designed to erode in these conditions first, before metal components of your jet pump outlets are seriously damaged.

Replacement Procedure

When the anode has eroded to approximately one-half its original size, it should be replaced. Ask your dealer for this service or you can do it yourself if you have a torque wrench of the proper type.

1)Unscrew the two mounting bolts that secure the anode to the jet pump outlet.

2)Clean the mounting-bolts threads, then coat them with Loctite® 242, available from your Yamaha dealer.

3)Install the new anode. Tighten the mounting bolts to specification.

Anode Bolt Torque:

50~80 kgf-cm (47~70 inch-pounds)

ANODE

Inspect the anodes each time the boat is removed from the water. It is normal for them to look corroded and rough. Replace the anodes when they are approximately one half of their original size.

•Failure to replace anodes when necessary can result in perma- nent damage to the jet pump out- lets and other metal components on the boat.

•Never paint the anodes. A coating of any kind will prevent the anode from functioning, exposing other components to galvanic corro- sion damage.
