DON'T BUY A "FAKE A LAKE" Try This and Save Money. 2003 Malibu 23 LSV Wakesetter run out of water. 

I could not get the Fake A Lake to work on my 2003 Malibu Wakesetter 23 LSV. I did some research and it sounded like I needed to change my impeller, I removed it and destroyed it in the process, but it looked completely fine, had to purchase a new impeller of course and I installed it.
After more research, it seemed the only other option to run my boat engine out of water was to purchase a flush pro.
This is a much cheaper and simpler option!
All you need is a garden hose!
