Customer Question

My 2005 Yamaha loses speed when I try to open it up

Hi and thank you for your question.
Which 2005 XLT Yamaha Wave Runner do you have? (Engine size)
Also, if you could provide additional information, it would speed the diagnostic process along.
How long has it been having this problem?
How many hours on the ski?
Are there any modifications to the engine or hull?
Have you done a compression test on the engine?
Has there been any service work, maintenance or repairs done on the ski recently?
Was it running fine one day then the next it started losing top speed, or was it running fine the last time it was ridden, then sat awhile, then was losing top speed the next time you took it out?
Thanks Customer
