INSTALLATION & INSPECTION

IMPORTANT: No modifications are to be made to the Jet-Drive without prior written permission from American Turbine, Inc. American Turbine jets are designed to propel watercrafts up to 50 mph without special modifications and safety equipment. For watercraft speeds above 50 mph the dealer or boat manufacturer must include the proper equipment and insure the operator has the proper instruction.

PRE-DELIVERY INSPECTION

The following inspection should be performed prior to jet drive operation. The same inspection should be performed by the user or selling dealer after the first 10- 20 hours of use and regularly thereafter every three months. If any items of the inspection list do not meet inspection guidelines, they should be corrected before using the jet drive.

1. Hand Hole Cover. Check to make sure that the hand hole cover is tightly fastened.

2. Steering. Check the steering by rotating the wheel right and left with the engine off and verify that the nozzle turns completely against the housing to which it is attached. Check all steering cable connections. These include the transom housing steering nut, the tiller arm-to steering tube connection, the tiller shaft set screw and the lower nozzle pin cap screw.

3. Reverse Shift Control. With the control in full reverse, the reverse bucket should be camped down tight against the nozzle and completely cover the nozzle's discharge opening. In full forward, the reverse bucket should clear the entire nozzle discharge opening. In neutral, the reverse bucket should cover about 3/4ths of the discharge opening. The reverse bucket controller should have a provision to lock it in the forward position so that the bucket cannot fall into the water stream.

4. Throttle. Check to see that the throttle is operating smoothly. On boats with a single lever control, the shift must be complete before the engine RPM s increase.

5. Transom Seals. There should be no leaks at the housing seal to the boat or the housing seal to the bowl.

6. AT-309 & TJ-309 Packing Gland Inspection. The packing gland should be inspected and adjusted if necessary. With the boat in the water and the engine running, tighten the packing gland nuts equally. Excessive tightening of the gland will result in heat damage to the shaft. Excessive leakage of the gland can result in poor low speed acceleration and possible water damage to the boat engine.

7. SD-309 & FW-309 Weep Hole Inspection. A weep hole is provided to indicate the condition of the mechanical seal. Water running out the hole is an indication of a failed seal or that there is a foreign debris between the seal faces i.e. fishing line. A blast of compressed air in the weep hole will sometimes clear the obstruction. If it continues to leak, consult the manufacturer.

8. Engine Cooling Connections. Check to make sure all hose connections are tight.
