TROUBLESHOOTING
•
Although all Avon Seasport Jet's are given a rigid inspection before shipment from
the factory, trouble may occur in operation. If this happens check the Jet boat in
accordance with the procedures given in the troubleshooting chart. If repair is
necessary, contact your dealer.
•
If replacement parts are necessary, use genuine Avon/Yamaha parts or the
equivalent. Remember that failures, which are the result of the installation of parts
or accessories, which are not qualitatively equivalent to genuine Avon/Yamaha
parts, are not covered by the limited warranty. Any problem in the fuel,
compression, or ignition system can cause poor starting or loss of power while
driving. The troubleshooting chart describes quick and easy procedures for
checking these systems.
