It will be on the back of the ski. My 09 is kind of buried in the tunnel area. Longer tube to the right of the nozzle. My 2010 is on the port stern. It looks like a drain plug in the hull but it is larger and a garden hose fits it.
I think I see what u r talking about. The tube is 5 inches long on the port side bottom left of pic, left hand side when looking at rear and into this cavity. Correct?
Saw another post, start, water on, then water off then motor off.
